Sen. Tom Carper joined his committee colleagues Sens. Gary Peters, D-Michigan; Maggie Hassan, D-New Hampshire; and Kamala Harris, D-California, in sending a letter to the Department of Justice inspector general calling for an inquiry into possible political interference with the FBI’s investigation into the President Donald Trump campaign’s alleged involvement with Russia during the 2016 presidential election.

“The attorney general’s recommendation and the president’s decision to remove Mr. (James) Comey in the midst of the FBI’s most sensitive criminal investigation threatens the integrity of the Department of Justice and poses grave injury to the rule of law,” the senators wrote. “Yesterday, the president told NBC News that he asked Mr. Comey if he was under investigation while he was actively considering whether or not to retain Mr. Comey as FBI director, a question that in itself undermines the FBI’s independence.

“The Office of the Inspector General is uniquely situated to defend the Department of Justice and the American people from this threat. For that reason, we request that you open an inquiry into whether there was political interference with the FBI’s investigation into the Trump campaign’s alleged collusion with Russian agents to disrupt the 2016 presidential election.”

In the letter, the senators called on the inspector general to investigate the allocation of resources for the Russia investigation; the intent and timing of former FBI Director James Comey’s termination, including the role of Attorney General Jeff Sessions in the termination despite his decision to recuse himself from the Russia investigation; and whether any actions of the DOJ or the White House constitute political interference in the FBI investigation.
