Remember when Nebraska Sen. Ben Sasse lost a Twitter bet last year against the Independent Journal Review's Benny Johnson after the University of Iowa football team defeated the Nebraska Cornhuskers?

He’ll be following through on his punishment — driving for Uber customers while wearing Iowa Hawkeyes gear — this weekend in Iowa.

Sasse told CNN's Jake Tapper during Sunday's “State of the Union” that he planned to drive in Iowa City, but family commitments will keep him in central Iowa.

"I don’t want to admit it anywhere, let alone on national TV, but Nebraska lost to Iowa last year in a football game, and I lost a bet,” Sasse said. “So I have to drive Uber in Iowa next weekend. So that’s the reason I’m going to be in Iowa.

"It’s about Hawkeyes and Huskers bloodletting on the football field and the aftermath of that.”

Sasse, a Republican, has driven for Uber once before, previously in Lincoln, Neb. CNBC.com reported in November 2016 that Sasse wanted to drive for Uber as a way to connect with constituents and to learn more about the changing economy.

TheHill.com reported that Sasse, who has a five-star rating as an Uber driver, cannot accept payment by law.
