The chair of the House Judiciary Committee is threatening to depose acting Attorney General Matthew Whitaker, suggesting he may have lied under oath last week when he testified to Congress about his communications with Donald Trump regarding the president’s former attorney, Michael Cohen. In a letter sent to Whitaker Wednesday, New York Democratic Congressmember Jerrold Nadler wrote, “[M]embers on both sides of the aisle found many of your answers to be unsatisfactory, incomplete or contradicted by other evidence.” This comes as the Senate is set to vote today on whether to confirm William Barr, President Trump’s nominee to replace Jeff Sessions as attorney general.
