The text messages, which were obtained by The Associated Press, were from a group chat involving Janicek and five other people, including the female staffer. At one point, he wrote that he had argued with her and then asked whether the campaign should spend money on “getting her laid.”

“It will probably take three guys,” he wrote, before describing in graphic detail an imagined group sex scene involving the female staffer.

He then tried walk back those comments as “a joke,” and texted an apology to the group.

“I’m going on no sleep and a bunch of exuberant excitement and I think I was out of line,” he wrote.
