Members of Congress, despite disagreeing on policy, generally treat each other with a baseline level of respect, even with members of another party. Generally.
According to a series of tweets, Ohio Rep. Joyce Beatty, 71, a Democrat and the chairwoman of the Congressional Black Caucus, asked Kentucky Rep. Hal Rogers, 84, a Republican currently serving his 21st term, to put on a mask before boarding the train that shuttles people to and from the House floor.
Instead, Rogers allegedly poked Beatty in the back before hurling an expletive at her.
