Cover-ups on top of cover-ups!

"In a statement Monday night, House Judiciary Committe Chairman Jerry Nadler said the decision to keep the aides from testifying was "a shocking and dangerous" use of executive privilege.

"The President would have us believe that he can willfully engage in criminal activity and prevent witnesses from testifying before Congress -- even if they did not actually work for him or his administration," the New York Democrat said. "If he were to prevail in this cover-up while the Judiciary Committee is considering whether to recommend articles of impeachment, he would upend the separation of powers as envisioned by our founders."

The White House's position on the testimony of Lewandowski, Porter and Dearborn adds to the growing fight between the Trump administration and the Judiciary Committee over the panel's investigation and its efforts to obtain testimony from those cited by Mueller. The White House has also asserted immunity over the testimony of former White House counsel Don McGahn, and the committee has sued in order to compel his appearance, which is still being litigated."
