I think Mueller is losing it. I think he may be in the early stages of dementia. Watch how confused he looks and add the fact that he needs a handler.
Alcohol tends to do that to people......
As a born again Christian (August 18, 1962) I wonder if, in the realm of the spirit, when someone like Mueller spends an entire career pretending to be a straight arrow, while actually committing all manner of treachery and perfidy and calumny; whether at some point the rotten blotches on their mind and soul might fester, and become rotten and their false persona fall apart...like ol’ Bob’s?
I noticed that as well! Deer in the headlight eyes. He started mumbling on the witness stand. Talk about a guilty soul!
