Newt Gingrich will make his first appearance with presumptive GOP nominee Mitt Romney on May 29 in Las Vegas.

NBC News has learned the former House speaker will attend a fundraiser for Romney at Trump Towers in Las Vegas Tuesday evening. Donald Trump will also attend.

The last time Gingrich and Romney were in Nevada together was in early February, amid a bitter fight for the nomination.

Rumors broke just days before the Feb. 4 Nevada caucuses – and were confirmed by several news outlets -- that Trump himself would endorse Gingrich. Hours later, however, the casino mogul endorsed Romney.

A joint public event with the two former competitors may occur next month.

With both sides eying one of the fastest-growing blocs in the American electorate, President Barack Obama's re-election campaign on Wednesday announced an aggressive outreach to Latino voters, pushing Democrats' reform proposals and casting Mitt Romney as "extreme" on immigration issues.

The new "Latinos for Obama" effort includes on-the-ground volunteer and staff outreach as well as Spanish-language ads slated to air in heavily Hispanic swing states Colorado, Florida, and Nevada.

Backers of the president hope that Romney's embrace of Arizona's controversial immigration law as well as his pledge to oppose the DREAM Act -- which would offer a path to citizenship for some children who were brought to the United States illegally at an early age -- will mobilize Latinos against the presumptive Republican nominee.

"This election is an opportunity in this country for the Latino community to send a message," said Sen. Robert Menendez, D-N.J., on a conference call announcing the new push. "The reality is that we look at this as the civil rights issue of our time."

Opposition to the DREAM Act is "insulting" to Hispanic families, added San Antonio Mayor Julian Castro, who -- echoed by campaign manager Jim Messina -- labeled Romney's positions "the most extreme nominee that the Republican party has ever had on immigration."

Republican Sen. Marco Rubio of Florida has pushed for a "conservative alternative" to the DREAM Act, which would allow some young illegal immigrants to stay in the United States but would prevent them from attaining citizenship. Messina said Wednesday that the president has been focused on reviving the original legislation, which failed in the Senate by a narrow margin late in 2010, but added that the White House would work to "find common ground" with those on the other side of the aisle. 

The Republican National Committee announced its own Latino-focused program earlier this week, launching community outreach directors in Florida, Colorado, Nevada, New Mexico, North Carolina and Virginia.  A key part of their message, said chairman Reince Priebus, is to highlight the impact the nation's sluggish economy has on the Hispanic community.

Hispanic voters favored Obama over Republican John McCain by an almost 2-1 margin in the 2008 presidential election. Nationally, the Hispanic vote in 2008 rose to 9 percent of the electorate, up from 8 percent in 2004, but turnout jumped by five points in swing states Colorado and Nevada and by nine points in New Mexico.

BOULDER CITY, NV – President Obama touted solar energy as an “industry on the rise” and condemned Republican skeptics of this power source in his first stop on a nationwide energy tour.

“This is an industry on the rise. It’s a source of energy that’s becoming cheaper. And more and more businesses are starting to take notice,” Obama said, noting that 16 solar projects have been approved on public land since he took office.

But, standing in front of a vast field of solar panels set against a Nevada mountain skyline, Obama criticized those politicians who he said “make jokes” about alternative energy.

Using a new favorite catch phrase for lawmakers he considers outdated, Obama said, “If these people were around when Columbus set sail, they’d be charter members of the Flat Earth Society.”

The president toured the Copper Mountain photovoltaic facility in Boulder City, Nevada – the largest of its type in the country – before making his remarks, which were intended to highlight one pillar of his “all-of-the-above” energy strategy.

The Copper Mountain solar panel site was constructed in 2010 and produces enough solar energy to power more than 17,000 homes, according to plant’s owner company Sempra Generation. Most of the homes it powers are in Southern California, not Nevada.

While the bulk of the project was financed with private money, it did receive about $40 million in federal tax credits – the sort of funding Obama said the federal government should continue to provide in order to jump-start emerging industries.

He acknowledged, however, that such government investments sometimes do not pay off – an indirect reference, perhaps, to the Solyndra solar power company that went bankrupt in 2011 despite receiving $535 million in federal stimulus loan guarantees.

“Each successive generation recognizes that some technologies are going to work, some won’t; some companies will fail, some companies will succeed,” Obama said.

But he likened such failures to the trail-and-error of now-established industries like automobiles and airplanes, which he noted once were both fledgling technologies themselves.

“Not every auto company succeeded in the early days of the auto industry. Not every airplane manufacturer succeeded in the early days of aviation.” 

Obama also compared the Copper Mountain solar facility to an earlier federal energy project – the Hoover Dam, for which Boulder City, just 20 minutes away, was originally constructed as a suburb for dam builders during the 1930s.

“Eight decades ago, in the midst of the Great Depression, the people of Boulder City were busy working on another energy project that you may have heard of. Like today, it was a little bit ahead of its time,” Obama said, referring to the dam. “Even today it stands as a testimony to American ingenuity, American imagination and the power of the American spirit.”

Perhaps coincidentally, Obama’s praise of the Hoover Dam came just days after the government-funded project was mentioned by Republican presidential hopeful Mitt Romney as an example of the kind of large-scale construction projects America is capable of.

“We once built the interstate highway system and the Hoover Dam. Today, we can't even build a pipeline,” Romney said Monday in Illinois, referring to the stalled northern portion of the Keystone oil pipeline.

(Obama’s energy tour is not considered by the White House to be an official campaign jaunt.)

LAS VEGAS -- Newt Gingrich had no comment about January's jobs figures at an event late Friday morning in Nevada because, the former House speaker explained, he hadn't seen them yet.

Gingrich was asked several times about this morning's jobs report, which showed the economy added over 240,000 jobs and the unemployment rate falling to 8.3 percent, while working the rope line following an event in which he assailed President Obama's economic record.

“I haven’t seen them yet,” he told reporters late morning and was overheard by some members of the press telling his deputy press secretary, "I don't know what to tell them on job numbers. I don't know what to say now. These people are driving me up the wall with this."

Gingrich would address the January figures shortly after the event concluded in a pre-taped interview with CNN.

"He's [Obama] gonna take credit for it. We've been in the longest deepest recession since the depression," Gingrich said. "I think he [Obama] will get some limited credit and it depends on how much the economy recovers and what the rest of the year looks like."

Gingrich took aim at Obama and his main Republican rival, Mitt Romney, at this morning's event, just a day before Saturday's Nevada caucus.

“It isn't good enough for the Republican Party to nominate Obama lite,” Gingrich said inside Stoney's Rockin Country bar a few miles from the Las Vegas strip.

The former House speaker, who frequently labels President Obama “the best food stamp president in history,” today took those remarks a step further and threw Romney in the mix.

“Obama is big food stamp, he's {Romney] little food stamp but they both think food stamps are okay,” Gingrich told the crowd, which had a couple hundred people in attendance. “I don't think food stamps are a future for America.”

The Speaker gave one of his more energetic speeches Friday, drawing a number of standing ovations on a day when he has just two public events scheduled.

On Wednesday morning, Gov. Romney made what some believe are controversial comments about the poor and Gingrich has continued to criticize Romney for “his boo-boo” and today labeled him as rich.

"We did not create Fannie Mae and Freddie Mac so rich guys like Mitt Romney and Goldman Sachs could make money," the speaker said.

SPARKS, NV -- Mitt Romney on Friday hailed news that the economy added over 240,000 jobs in January as "good news," while blaming President Obama for making the economic recovery more difficult.

Romney, who's made criticism of the president's economic stewardship a centerpiece of his campaign, engaged a delicate political balancing act between seeming upbeat about the news, which also saw the unemployment rate drop to 8.3 percent, while making the case that Obama's leadership has made the recovery slower and more painful.

"This recovery has been slower than it should have been, people have been suffering for longer than they should have had to suffer. Will it get better? I think it’ll get better. I don’t know how long it’s going to take," Romney said  at a business roundtable outside Reno. " We got good news this morning on job creation in January. I hope that continues, we get people back to work."

“But this president has not helped the process," Romney continued. "He’s hurt it."

For Romney, reacting to news as he did today is a bit like walking through a political minefield. Any economic indicators that show a stronger or swifter economy undercut Romney's message that Obama's policies have made, or are making, the economy weaker.

"This has been a tough time. And I know the president didn't cause this downturn -- this recession. But he didn't make it better either. He made it worse," Romney said. "He made it worse because instead of focusing his energy on the economy and getting people back to work, he used his mandate being elected-- he used that to put through a series of programs that he and his base and his friends thought were important but frankly made it harder for our economy to recover. And so we've suffered."

This morning's event, the first of three planned campaign stops across Nevada today, had a bit of a back-to-the-future feel. Roundtable discussions with business leaders were a regular feature of Romney's fall campaign in New Hampshire and Iowa, but have fallen out of favor as the campaign has held more rallies and large events since voting began in January.

Also hearkening back to Romney's fall campaign strategy? The frontrunner made no mention of any of the remaining GOP candidates in his hourlong campaign stop.

Donald Trump formally endorsed Mitt Romney for president on Thursday, describing the former Massachusetts governor as "tough" and "smart" and the best pick in the GOP primary.

Trump and Romney appeared together in Las Vegas to announce the endorsement, which drew heavy media coverage.

"It is a real honor and privilege to endorse Mitt Romney," Trump said in brief remarks. "Mitt is tough, he's smart, he's sharp. He's not going to allow bad things to continue to happen to this country we all love."

Romney said in response: "There are some things that you just can't imagine in your life. This is one of them," adding that it means a "great deal" to have the billionaire's support.

The endorsement follows a bizarre period of time in which several major news outlets -- including the New York Times and Associated Press -- had initially reported that Trump had been planning to endorse Newt Gingrich. The former House speaker had been one of only two candidates to agree appearing at a debate the "Apprentice" host had planned, but which never came to pass. Romney declined attendance.

Former Pennsylvania Sen. Rick Santorum (R) said he didn't think the Trump endorsement matters, but added on KDWN radio that if Trump "wants to endorse the person who's most in line with his thinking with respect to the major issue of this economic problem that we're involved in, he should endorse Rick Santorum."

For their part, Democrats seemed to take a degree of joy in the Trump spectacle.

"It really wouldn't be surprising if Donald Trump endorses Mitt Romney, because they both like firing people, and they both made millions doing it" Florida Rep. Debbie Wasserman Schultz, the chairwoman of the Democratic National Committee, said on msnbc. "Donald Trump is such a cartoon character, no matter who he chooses, it's like Bugs Bunny endorsing ... It's really kind of a non-news event."

It's reflective of the media whirlwind to have surrounded Trump's game of footsie with Republican politics over the past year.

Trump had initially thought about running for the GOP nomination last spring. He talked publicly about the possibility of running and even visited New Hampshire. The flirtation coincided with the broadcast of last spring's season of "The Apprentice" on NBC. (NBC is a co-owner of mnsbc.com, along with Microsoft.) Trump had initially promised to make clear his intentions in the show's season finale, but ultimately demurred, and made the announcement separately.

Trump had additionally been one of the most prominent figures to voice suspicions that President Obama had not actually been born in the United States, and, thusly, was constitutionally ineligible to be president. Obama eventually relented and released his long-form birth certificate on April 27, 2011, verifying he was born in Hawaii. Obama made light of the situation at the White House Correspondents' Association dinner on May 1, deriding the media for giving voice to “carnival barkers” like Trump, only to announce the next day that Osama bin Laden had been killed in a daring raid in Pakistan -- planning of which had been ongoing during the annual dinner.

But the discussion of "birther" theories over the course of last spring appears to have harmed Trump in the eyes of the public; Trump had a 26 percent favorable rating in a February 2011 NBC News/Wall Street Journal poll, and a 29 percent unfavorable rating. By mid-May, the point at which the real estate magnate announced he wouldn't be running, a Suffolk University poll found that Trump had a 70 percent unfavorable rating, while just 18 percent of Americans had a positive opinion of Trump.

It's also not incredibly clear what, if any, impact the Trump endorsement will have on the trajectory of the race, in Nevada's caucuses on Saturday, or beyond. Romney had already led, at 45 percent, in a poll of likely Nevada caucus-goers released Thursday. He's followed by Gingrich at 25 percent, Santorum at 11 percent and Texas Rep. Ron Paul at 9 percent.

Still, the reality television star continued to play an out-sized role throughout the 2012 cycle. All the Republican candidates visited Trump through the course of last summer with the exception of former Utah Gov. Jon Huntsman.

"I think his infusing himself into the dialogue really dumbs down and makes less consequential the very important issues that we must be discussing to get this country back on its feet again," Huntsman said on Fox News in December.

One of the most intensely covered media events of 2011 came when former Alaska Gov. Sarah Palin went out for pizza with Trump in Manhattan during a stop on her bus tour of the Northeast, a journey meant to stoke speculation about her own presidential aspirations. When Romney visited Trump, he snuck in and out of the billionaire's headquarters without being captured by staked-out cameras.

LAKEWOOD, CO -- Rick Santorum is fighting to portray himself as the top conservative alternative to Mitt Romney, a message he'll take to voters in a series of forthcoming caucuses.

At Colorado Christian University on Wednesday, the presidential hopeful said Newt Gingrich has had more success courting voters in early primary states because of an incorrect notion that the former House speaker is in a better position to challenge Mitt Romney. But, Santorum charged, Gingrich's inability to capitalize on a decisive South Carolina primary victory in Florida shows he does not have the support to challenge the former Massachusetts governor.

"In Florida, Newt Gingrich had his opportunity," Santorum said in Las Vegas on Tuesday as Sunshine State returns showed Gingrich finishing second.  "He came out of the state  of South Carolina, he came out with a big win and a lot of money,  and he said 'I'm going to be the conservative alternative. I'm going to be the anti-Mitt.' And it didn't work. He became the issue."

The former Pennsylvania senator is taking a renewed focus on Gingrich after losing to his rival in the two most recent primary contests. But Santorum faces a tough balancing act between steering clear of the personal attacks candidates have leveled against each other, while drawing contrasts with his GOP foes. One of Gingrich's chief liabilities among conservatives are the ethics charges leveled against him as speaker and his rocky marital history.

Newly-released television and radio ads take aim at Gingrich, in both cases questioning his conservative credentials. Still, Santorum claims to still be remaining above the fray by focusing on issues, not personal matters.

"What I talked about is policy, I didn't attack the speaker for working for a company or, you know, things that he did in his past in his life.
I went out and focused on the policy differences between Speaker Gingrich and me," he said. "I think that's fair game."

But it was just a day earlier when the GOP hopeful, working to remain relevant in the nominating contest, said Florida's results prove Republicans need to have a candidate without "personal baggage."

Now Santorum is tasked with convincing the electorate that he can effectively take on Romney, after losing to Gingrich by substantial margins. His focus now turns to Colorado, Nevada, and Minnesota -- caucus states where he has the opportunity to pick up delegates without having to win outright.

"If Newt's out of the race, all of his votes come to me," Santorum said. "They aren't voting for Newt not because he's the best candidate, it's because they think he can win."

And despite the tough path ahead, the candidate said he has no plans of quitting.

"This race is just beginning. Only four states have spoken. There are 46 others," he said.
