House investigators wrote White House Counsel today to demand that the White House release documents requested under subpoena and indicated a willingness to issue new subpoenas for testimony, in addition to threatening “to take the necessary steps to ensure that there is no further obstruction of our investigation.”

“It is clear that you have numerous other documents in your possession which are responsive to the subpoena,” Energy and Commerce chair Fred Upton, R-Mich., and Oversight and Investigations subcommittee chair Cliff Stearns, R-Fla., wrote to White House Counsel Kathryn Ruemmler. “You are in violation of the subpoena and must immediately produce all responsive documents or the committee will be forced to take further steps to ensure compliance wth the subpoena.”
