Tomorrow in Houston, former President George H.W. Bush will appear with Mitt Romney and formally offer his endorsement of of the former Massachusetts governor for president, the Romney campaign confirms to NBC News.
The formal endorsement at the former president's office in downtown Houston comes after a series of quasi-endorsements by Bush -- in the form of newspaper interviews and public comments praising Romney, and on the heels of the recent endorsement by Bush's son Jeb, the former governor of Florida.
In Houston, Romney will appear before the media with Bush and his wife, former First Lady Barbara Bush, for the first time since the couple told the Houston Chronicle they were supporting Romney. The couple has been somewhat active in supporting Romney's candidacy already, with Mrs. Bush recording robo-calls for Romney in Ohio and Vermont.
"Mitt and Ann are dear friends of George and Barbara. Governor Romney is honored to have their endorsement," a Romney aide told NBC News this morning.
