"The Mueller report describes several acts that satisfy all of the elements for an obstruction charge: conduct that obstructed or attempted to obstruct the truth-finding process, as to which the evidence of corrupt intent and connection to pending proceedings is overwhelming. These include: · The President’s efforts to fire Mueller and to falsify evidence about that effort; · The President’s efforts to limit the scope of Mueller’s investigation to exclude his conduct; and · The President’s efforts to prevent witnesses from cooperating with investigators probing him and his campaign."
