North Carolina Rep. Renee Ellmers became the first Republican incumbent to lose a primary on Tuesday just days after Donald Trump endorsed her.

Trump backed Ellmers in a robocall that went out on Saturday calling her a “fighter” who could help him get things done in Washington. It was his first official congressional endorsement.

But on Tuesday, she lost in a primary to Rep. George Holding after redistricting forced the two North Carolina incumbents to compete for the seat.

Ellmers suffered when Susan B. Anthony List, a group dedicated to electing anti-abortion Republicans to office, endorsed her opponent. SBA was upset when Ellmers attempted to stall a 20-week abortion bill that had the caveat that a woman subject to rape or incest would have to report it to authorities to qualify for an exemption from the ban.

Ellmers' loss also came the same day as a video of her telling a North Carolina Republican woman that she had gained some weight.

“You’re eating a little bit too much pork barbecue. Whoo!” Ellmers said as she walked past.

Former American Idol star Clay Aiken, who lost his challenge to Ellmers in the 2014 election, wasted no time weighing in on the results.
