White House counsel Pat Cipollone wrote in a letter to the Democratic chairman of the House Judiciary Committee that it would be a “reckless abuse of power” for House Democrats to adopt articles of impeachment and “would constitute the most unjust, highly partisan, and unconstitutional attempt at impeachment in our Nation’s history.”
The letter did not explicitly state that the White House would not participate in any House proceedings moving forward, but gave the indication that it would not cooperate and would instead shift its focus to defending President Trump in a potential Senate trial.
