Donald Trump is spending part of his Sunday afternoon behind the counter at a Pennsylvania McDonald’s. The former president, who has frequently said he loves the chain’s food, donned an apron to work the fry machine and hand food to customers at the drive thru. It’s an attempt to bring attention to his unfounded allegations that his opponent, Vice President Kamala Harris, did not work there during college.

When asked why he wanted to come to the fast food restaurant, Trump responded, “I like McDonalds. I like jobs. I like to see good jobs and I think it’s inappropriate when someone puts down that they worked at McDonalds… She [Harris] never worked at McDonalds.”

“Should I give them extra salt?” Trump asked a McDonald’s worker while salting fries.

Rolling Stone has reached out to the Harris campaign for comment. A campaign official told CNN that she worked at a McDonald’s in Alameda, California, in the summer of 1983 while a student at Howard University, working the register as well as the fry and ice cream machines.

“I did fries. And then I did the cashier,” Harris said on Drew Barrymore’s talk show in April.

Trump, who recently complained that he “used to hate to pay overtime” to his employees, has proposed a policies that would end taxes on overtime and tips. Harris has proposed a similar no tax on tips policy for hospitality and service industry workers.

“I know a lot about overtime. I hated to give overtime, I hated it. I’d get other people—I shouldn’t say this, but I’d get other people in. I wouldn’t pay,” Trump said at a Pennsylvania rally last month, basically confessing to committing wage theft.

Reacting to Trump’s remarks at the time, the Harris campaign said in a statement to The Daily Beast, “Donald Trump is finally owning up to it: He’s built an entire career on screwing over workers. It’s exactly what he did in the White House — trying to rip away tips and overtime pay for millions of workers — and exactly what he plans to do in a second term.”
