Rep. Renee Ellmers (R-NC) was caught on video mocking a former staffer about her weight as she faced an uphill re-election battle on Tuesday, WCNC-TV reported.

"Typical Renee," said the target of Ellmers' insult, Maggie Sandrock. "She has become a mean girl on steroids in my view."
The footage shows Ellmers walking by Sandrock -- who went from working on Ellmers' previous campaigns to working for her GOP primary opponent, fellow Rep. George Holding -- and telling her, "You're eating a little bit too much pork barbecue. Whoo!"
Ellmers did not mention their prior working relationship when asked about it by WNCN, while refusing to apologize for her remark.
"Yeah, I know her," she said. "She's actually, I think she lives in Lillington, but she's part of the Republican Party."
While Ellmers said she considered Sandrock a friend, she said she was not sure if the feeling was mutual.
"I would consider her a friend, but certainly not a good one," said Sandrock. "Good friends don't tell you you're fat or you're getting fat. They may say, 'Everything going well Maggie? You look a little stressed out.' But they don't say, 'Too much pork barbecue, Maggie.'"
Bloomberg News reported that Ellmers was trailing both Holding and Greg Brannon in the primary, garnering only 21 percent of the vote.
