The congressman, they said, was volatile. When he was angry, they added, Mr. Farenthold would berate them, sometimes sweeping his arm across his desk, knocking its contents to the floor, and threatening to fire people. Ms. Daniels, who has worked for Mr. Farenthold since March, said she had never witnessed such behavior, adding, “All the staff get along here very well.”

The refrigerator in the “bullpen” — the open area where aides worked — was filled with beer, and sometimes happy hour would begin at 4:30 p.m., which his aides called “beer-thirty.” Ms. Peace said women would discuss which male lobbyists had texted them pictures of their genitals, and both men and women would talk about strip clubs and whether certain Fox News anchors had breast implants.

“There were numerous lewd comments that were made either about female reporters’ breast size, or other reporters’ breast size as well as female lobbyists and their appearance that would go on,” the other former aide said. “On any given week you were prone to either ridicule, rude comments, acts of aggression or rage.”
