"Once in office, Donald Trump serially obstructed justice by interfering with the Mueller investigation and demanding that his attorneys and advisers lie about his conduct and manufacture evidence to obscure his conduct. His attempted disruption of the investigation into then-national security adviser Michael Flynn; the firing of then-FBI director James Comey; his efforts to fire Robert Mueller and derail the investigation; his insistence that then-White House counsel Don McGahn lie about the efforts to remove or disrupt Mueller; and his efforts to disrupt the gathering of testimony from former campaign chairman Paul Manafort and former Trump attorney Michael Cohen individually and collectively blow right past the constitutional standard of “high crimes and misdemeanors.” These were deeply damaging bold-face crimes committed in the presence of testifying witnesses.
