"We have asked the Department to provide us this information before the Committee’s open hearing scheduled for March 20," a House Intelligence Committee spokesperson said. "If the Committee does not receive a response by then, the Committee will ask for this information during the March 20 hearing and may resort to a compulsory process if our questions continue to go unanswered."
