Santorum Unaware of Campaign Motto's Origin

Rick Santorum's Thursday announcement that he will build his presidential campaign war chest under the slogan "Fighting to Make America America Again" hit a snag when ThinkProgress pointed out it bears a striking resemblance to a poem by Langston Hughes.

During a Friday afternoon New Hampshire appearance, Santorum was asked by the site's Lee Fang whether he was aware that the slogan was lifted from the Harlem Renaissance poet's "Let America Be America Again." A gay rights advocate, Hughes wrote works including "Cafe: 3 a.m.," which criticizes a police raid on a gay establishment.

The antigay pol replied that he had "nothing to do" with the slogan.

"I didn't know that. The folks who worked on that slogan for me didn't inform me that that's where it came from, if in fact it came from that," Santorum said.
