Just before the vote, Pocan, the co-chair of the Congressional Progressive Caucus, inflamed tensions further when he called the Problem Solvers Caucus — a bipartisan group of moderates that pushed Pelosi to take up the Senate bill — the Child Abuse Caucus…

Reps. Max Rose (D-N.Y.), and Dean Phillips (D-Minn.), both members of the Problem Solvers Caucus, confronted Pocan on the House floor over his tweet. According to sources familiar with the conversation, Rose used expletives, and Pocan said he did not apologize.

“I said, how come you can’t stay 24 hours to do your job?” Pocan said of his retort to Rose on the floor. “He said, ‘My mother thinks I’m a child abuser.’ I said, ‘I’ll tell your mother you’re not a child abuser.’”…

“Mark’s tweet just speaks to why everyone hates this place. He’s just trying to get retweets. That’s all he cares about,” Rose told POLITICO.
