Charles Krauthammer named H. R. McMaster his “loser of the week” due to his damaged reputation, and then he explained why the winner of the week was Robert Mueller:

My loser: H. R. McMaster, the national-security adviser. On the night of the report of Trump spilling secrets to the Russians, he was one of several trotted out to say the story was false. The next day, he is contradicted by Trump who said he was within his rights to say what he said, implying that he did say it and the story was true. McMaster holds a press conference the next day, where he had to reconcile the irreconcilables. It was a sad sight for a man who spent decades establishing a reputation for integrity and consistency.

My winner is Robert Mueller, who is going to be the chief investigator for the Russia probe. He is now the man who is in charge who has a mandate to investigate essentially anything and is politically untouchable, cannot be fired. Technically he can; politically he can’t. He’s the most powerful man in Washington.
