Sen. Chuck Grassley, Chairman of the Judiciary Committee, is demanding answers over who funded the infamous ‘Trump Dossier’ compiled by a British-spy, and whether any of that money can be traced back to the FBI.

Sen. Grassley sent a letter to Fusion GPS, the company that allegedly hired British-spy Christopher Steele to compile the report, seeking information on Steele, who hired the firm, and if there was any transfer of funds or information between Fusion and the FBI.

"When political opposition research becomes the basis for law enforcement or intelligence efforts, it raises substantial questions about the independence of law enforcement and intelligence from politics," Grassley said in his letter.

The relationship between Christopher Steele, the Federal Bureau of Investigation, and whether this material was used as political opposition during the 2016 election has gained increased scrutiny in recent weeks.

The Washington Post reported in February that the FBI had reached a tentative agreement to pay Steele for the ‘dossier’, but that deal eventually collapsed.

Sen. Grassley has also sent a letter to FBI director James Comey, asking for all records that relate to any possible agreements between the Bureau and Steele.
