Paul, Santorum, Bachmann, Gingrich y Huntsman también niegan haberle pasado la historia a POLITICO

The Hill:

"We plan to go after Mr. Cain, and Romney and Perry for that matter, over issues like their support of bailouts and TARP," said Ron Paul spokesman Jesse Benton. "Our campaign stays away from the personal attacks and mud slinging."

Hogan Gidley, a spokesman for Rick Santorum, said they "had absolutely nothing to do with it."

The campaign of Rep. Michele Bachmann (R-Minn.) also denied any involvement. "It absolutely did not come from us," Bachmann spokeswoman Alice Stewart said.

Spokespeople for former House Speaker Newt Gingrich (R-Ga.) and former Utah Gov. Jon Huntsman (R) also said their campaigns had no involvement in pushing the story.
