Trump is also accused of obstructing the impeachment inquiry by instructing witnesses and agencies to ignore subpoenas for documents and testimony, as well as intimidating and tampering with witnesses.

"No other President has flouted the Constitution and power of Congress to conduct oversight to this extent," reads the report. "If left unanswered, President Trump's ongoing effort to thwart Congress' impeachment power risks doing grave harm to the institution of Congress, the balance of power between our branches of government, and the Constitutional order that the President and every Member of Congress have sworn to protect and defend."

"The decision to move forward with an impeachment inquiry is not one we took lightly.  Under the best of circumstances, impeachment is a wrenching process for the nation.  I resisted calls to undertake an impeachment investigation for many months on that basis, notwithstanding the existence of presidential misconduct that I believed to be deeply unethical and damaging to our democracy.  The alarming events and actions detailed in this report, however, left us with no choice but to proceed."
