Comey’s appearance on Capitol Hill comes a day after senior national security officials repeatedly ducked questions by Senate Intelligence Committee members over whether President Trump asked them to try to influence former FBI Director Comey’s investigation. Director of National Intelligence Dan Coats repeatedly declined to comment when asked about a Washington Post report that Trump asked him to pressure Comey to ease up on his probe into Michael Flynn. And Maine independent Senator Angus King pressed unsuccessfully for NSA Director Michael Rogers to answer questions about the report.

Sen. Angus King: “I don’t understand why you’re not answering our questions. You can’t—when you were confirmed before the Armed Services Committee, you took an oath: Do you solemnly swear to give the committee the truth, the full truth, and nothing but the truth, so help you God.”

Michael Rogers: “I do.”

Sen. Angus King: “You answered yes to that.”

Michael Rogers: “And I’ve also answered that those conversations were classified, and it is not appropriate in an open forum to discuss those classified conversations.”
