Cain camp says it's raised more than $1 million since Sunday night

Since Sunday night, when the story broke about the sexual harassment allegations surrounding Herman Cain, his campaign says it has raised more than $1 million.

Since IowaFund.com was launched this morning at 6, it has pulled in $100,000, the campaign said.

NBC’s Kelly O’Donnell reported this morning on an email solicitation to supporters from Cain’s Iowa chairman Steve Grubbs. In it, he said, "The other Republican candidates, the liberal media, and even President Obama have begun to publicly attack Mr. Cain because they are intimidated by his ‘9-9-9 Plan’ and his ability to connect with Americans. As Mr. Cain continues to pull away in the polls, we expect the attacks to continue."

Cain spokesman J.D. Gordon told NBC, "Mr. Cain's supporters around the country have rallied around him, and we have been encouraged by their strong showing."

As a result, the Cain campaign has gone up with ads on conservative talk radio shows of Rush Limbaugh and Sean Hannity.
