An FBI informant connected to the "Uranium One" scandal said that Russian nuclear executives sent money to the United States in hopes it would influence the Obama administration and then-Secretary of State Hillary Clinton, according to a report Wednesday.

In written testimony obtained by the Hill, the informant, Douglas Campbell, told Congress that Russian nuclear officials told him that Moscow hired American lobbying firm APCO Worldwide with a $3 million annual lobbying fee in hopes of influencing Clinton to "reset" U.S.-Russia relations while supporting former President Bill Clinton’s charity efforts.

“The contract called for four payments of $750,000 over twelve months,” Campbell explained. “APCO was expected to give assistance free of charge to the Clinton Global Initiative as part of their effort to create a favorable environment to ensure the Obama administration made affirmative decisions on everything from Uranium One to the U.S.-Russia Civilian Nuclear Cooperation agreement.”

When asked for comment, a spokesperson for APCO said that their work with the Clinton Foundation and Russia are not connected in any way and their work with Russia did not involve Uranium One.

A spokesperson for Clinton said that Campbell’s testimony is a distraction from the Trump-Russia investigation.

Campbell testified before staff from the Senate Judiciary, House Intelligence and House Oversight, and Government Reform committees for several hours on Wednesday and Democrats are now pushing for a transcript from that testimony to be publicly released.
