Dude, you are clearly not reading the thread. The letter was sent by his former chief of staff, Adam Jentleson, who publicly stands by its contents. (The doctor it was sent to was Dr. David Williamson, although that’s not really relevant since obviously he hasn’t commented).
The NBC news article Spice Weasel linked to in the post above yours is
based on interviews with 18 former Fetterman staffers, Pennsylvania officials and congressional lawmakers and staffers
And it’s been demonstrated that he’s not doing his job based on public records. Or do you think the official reports of attendance at Senate committee meetings and roll call votes have been altered by tEh cOnsPirAcy?
On to today’s breaking news, where an article in The Hill cites three Democratic Senators expressing concern about Fetterman’s mental health and saying that Senate Democrats are having frequent conversations about how to help him (yes, they’re unnamed, so if you want to think a Hill reporter would just make that up, go for it).
For named sources, Sen. Dick Durbin, Senate Democratic whip, says that Fetterman "has largely withdrawn from casual interactions with Democratic colleagues, and that due to his frequent absences, Durbin "hasn’t developed a relationship with him, which I usually do.
Also,
Former Pennsylvania Rep. Ron Klink (D) said Fetterman’s office appears to be suffering from a high rate of staff turnover and voiced his own frustration over not getting calls back when he asked for Fetterman’s help on certain issues, such as health care topics and the cleanup of toxic coal ash in Pennsylvania.
I hadn’t been aware that Fetterman actually isn’t allowed on the Senate floor except during votes, because he refuses to comply with the dress code that the Senate unanimously put in to place specifically to stop him from showing up in cargo shorts. So he values his cargo shorts more than the opportunity to interact with his colleagues? (FTR I think the Senate was being stupid and petty to pass a dress code, but it seems like a very odd choice of a hill to die on)
