Trump has now admitted sharing "facts" with the Russians, something that was vehemently denied yesterday by Tillerson and McMaster. Tillerson lost his credibility a while ago. McMaster was pushed in front of the press yesterday because he was the last person in the White House who could be trusted, and now his integrity and reputation, built over decades of service, are in ruins. His choices are to resign immediately or to swallow his pride and hang on, hoping that the 25th Amendment will be invoked soon.
