Donald Trump wants to do everything he can to prevent House Democrats' investigation into the murky aspects of his presidency. On Monday, he sued the chairman of the House Oversight Committee in a desperate attempt to prevent a summons of his financial records, and now the White House has ordered a top security official not to comply with a summons from the house requesting an interview. Carl Kline, who was responsible for the security clearance and is now working in the Department of Defense, was ordered late Monday to not appear on Tuesday. He claimed that Democrats were looking for access to confidential information. Elijah Cummings, chairman of the House Oversight Committee, said he could try to keep Kline in contempt of Congress if he did not appear for the interview. Michael Purpura, Trump's attorney, said the subpoena "unconstitutionally interferes with fundamental interests of the executive department." Kline's lawyer said his client would listen to his employer. Kline approved Jared Kushner's safety clearance, although several careers were taken by career members.
