Trump says released Republican memo 'totally vindicates' him in Russia probe

President Trump claimed "no collusion" and "no obstruction" in a tweet.

The four-page memo was written by Republican staff of the House Intelligence Committee and released Friday -- despite "grave concerns" expressed by the FBI over its being made public -- after Trump declassified it and approved its release without redactions by the House committee.

The president's tweet Saturday morning refers to the Russia investigation as a "Russian witch hunt" and asserts that there was "no collusion" and "no obstruction."

McCain of Arizona said, "The latest attacks on the FBI and Department of Justice serve no American interests – no party’s, no president’s, only [Russian President Vladimir} Putin’s. The American people deserve to know all of the facts surrounding Russia’s ongoing efforts to subvert our democracy, which is why Special Counsel Mueller’s investigation must proceed unimpeded."
