Three Republican lawmakers have introduced a resolution calling for special counsel Robert Mueller, who is investigating Russian interference during the 2016 election.
They claim that there is a conflict of interest, as Mr Mueller was director of the FBI when approval was given for an agreement granting a Russian company access to US uranium.
Approval was granted for the Russians to buy Canadian energy company Uranium One, who owned about 20% of US uranium supplies.
The group of Republicans claim that despite evidence of corruption, the FBI did not bring any charges.
They say that he lacks impartiality, and should recuse himself from the investigation, which is completely unrelated to the uranium deal.
“These deeply troubling events took place when Mr. Mueller was the Director of the FBI. As such, his impartiality is hopelessly compromised,” said Florida Rep. Matt Gaetz, who introduced the resolution.
“He must step down immediately.”
The Republicans are divided on the issue of special counsel Mr Mueller, with some calling for his removal and some moving to protect him from political interference.
Senator Lindsey Graham has co-authored one of two bills that would see a three-judge panel have the power to decide on whether termination of Mr Mueller was unwarranted.
Mr Mueller has backing from many Democrats and Republicans, in a rare moment of bipartisanship between the two parties.
