“Hey, everybody. It’s my first day at McDonald’s. I’m looking for a job,” Trump said as he entered the store in Feasterville-Trevose, Pennsylvania.

Outside, thousands of supporters gathered on the street across from the store to watch.

The Republican presidential candidate stopped by the store in suburban Philadelphia on Oct. 20 to fry fries and deliver food to customers in their cars.

“It’s fun, I could do this all day,” Trump said. “I don’t mind doing it. I think I’ll go back and do it again.” Trump said the McDonald’s operation was a jab at his opponent Kamala Harris. Harris said she worked at fast food chains while attending college in California, but Trump didn’t believe her.

Trump worked at the store for about 15 minutes, delivering food and chatting with customers and employees.

“I’ve been working at McDonald’s for 15 minutes longer than Kamala (Harris). She never worked here,” he said.

He also joked that he would send fries to Harris for her birthday. He said that if the upcoming election was held fairly, he would accept the results.

Harris’s campaign later issued a statement saying that Trump had lied about Harris never working at a fast food restaurant. It also said that the billionaire former president “doesn’t understand what it’s like to work for a living.” Harris told Reuters that Trump’s performance showed the tycoon was desperate.

Harris will need strong results in Detroit and Atlanta, as well as their surrounding areas, to win Michigan and Georgia. Trump is taking advantage of polls showing a tight race but his standing has improved.
