The author of "Clinton Cash" appeared on "Fox & Friends" this morning to react to a probe into potential “conflicts of interest” for Hillary Clinton and the Obama administration regarding the 2010 approval of a controversial uranium deal with a Russian company.

Peter Schweizer said a recent report in The Hill revealed that the FBI had evidence as early as 2009 that Russian operatives used bribes, kickbacks and other dirty tactics to expand Moscow’s atomic energy footprint in the U.S.

"Involved in that is a witness, an American businessman, under a gag order, who says that he heard and has information about efforts to bribe the Clintons involving the deal," Schweizer said.

That witness' attorney, Victoria Toensing, told The Hill her client was blocked by the Obama Justice Department from telling Congress about conversations and transactions he witnessed related to the Russian nuclear industry's efforts to win favor with the Clintons and to influence Obama administration decisions.

Brian Kilmeade said it's time for the Trump Justice Department to lift that gag order, so Congress and the American people can discover what he knows.

"There is absolutely no reason, I think, any justification, for this guy to be under a gag order anymore," Schweizer said. "Let him testify before Congress, let him go to the media and tell his story. And then people can decide what they think about what he has to say."

He noted that Senate Judiciary Committee Chairman Chuck Grassley (R-IA) announced this week that he is launching a probe into the controversial deal.

"He wants to get to the bottom of how this actually happened," Schweizer said.
