Sen. Ron Johnson, the chairman of the Senate Homeland Security Committee, is seeking authority to subpoena Stefan Halper, the former Cambridge professor who worked as an FBI confidential source during the Trump-Russia probe.
The Senate panel will hold a vote Wednesday regarding subpoenas for 41 witnesses Johnson wants to interview as part of a broad review of the FBI’s investigation of the Trump campaign and other intelligence-gathering activities regarding Trump associates.
The list includes Halper and his FBI handling agent, Steven Somma. Michigan Sen. Gary Peters, the top Democrat on the committee, wrote in a letter to Johnson on Monday that he opposes granting the subpoenas.
Republicans have questioned the FBI’s relationship with Halper, who has worked for four Republican administrations.
The FBI tapped Halper to meet with and secretly record three Trump campaign advisers: Carter Page, George Papadopoulos and Sam Clovis. (RELATED: EXCLUSIVE: A London Meeting Before The Election Aroused George Papadopoulos’s Suspicions)
