There are new revelations in the investigation into the controversial Uranium One deal, with an FBI informant telling lawmakers Wednesday that Russia paid millions to a U.S. lobbying firm in hopes of influencing the Hillary Clinton-run State Department.

In a story first reported by The Hill, Douglas Campbell informed three congressional committees that Moscow hired APCO Worldwide to "provide in-kind support for the Clintons’ Global Initiative." The information came from Russian nuclear officials, Campbell said.

Campbell's attorney, Victoria Toensing, said on "America's Newsroom" Thursday that APCO is a firm "with all kinds of former Clinton staffers on it" and was paid $3 million.

"That's a lot of money for a year of lobbying. They were going to do some kind of lobbying on some issues, but they were also expected to do lots of in-kind work for the Clinton Foundation," she said.

In response, Hillary Clinton's spokesman Nick Merrill dismissed the new report as a "charade."

"Just this week the committee made clear that this secret informant charade was just that, a charade," said Merrill. "Along with the widely debunked text-message-gate and Nunes' embarrassing memo episode, we have a trifecta of GOP-manufactured scandals designed to distract from their own president's problems and the threat to democracy he poses."

Toensing defended her client's credibility, saying the truth is on his side.

"He came out because he thought he was dying from cancer and he wanted his story to be told. ... They can go attack all they want to. He's got the truth, he's got briefings, the FBI has all kinds of videotapes," she said.

Toensing said the Russians believed they had "died and gone to heaven" when Clinton became secretary of state in 2009 and at that point, they began planning the Uranium One purchase.
