Pennsylvania Sen. John Fetterman, the lawmaker known for his unconventional and irreverent brand of politics, is in the news again after a blowup at a closed-door meeting with union allies and former staff aides who aired concerns about his mental health.

The Pennsylvania senator began repeating himself, shouting and questioning why 'everybody is mad at me,' 'why does everyone hate me, what did I ever do' and slamming his hands on a desk, say AP sources.
