Minnesota Gov. Tim Walz (D), the Democratic vice presidential nominee, on Monday accused former President Trump of disrespecting McDonald’s workers by pretending to work at one of its restaurants Sunday.

Trump took several pictures in a McDonald’s apron and red tie over the weekend, as he fried fries and served McDonald’s food to secret service vetted supporters in an effort to troll Harris for saying she worked at the fast food chain for a summer while attending college. Trump has repeatedly accused her of lying about having worked there.
