NEW YORK (AP) — Former President Donald Trump commemorated the 20th anniversary of the Sept. 11 attacks by visiting a fire station and police precinct in New York, where he criticized his successor for the way he pulled out of Afghanistan last month.

Trump skipped joining President Joe Biden and other past presidents at official 9/11 memorial ceremonies Saturday at the World Trade Center and in Shanksville, Pennsylvania.

Instead, he traveled several blocks from his Trump Tower building in Manhattan to the 17th police precinct and the neighboring fire station. Speaking to officers, Trump criticized the withdrawal from Afghanistan and expressed surprise about why it hadn’t come up in other 9/11 memorial speeches. “It was gross incompetence,” he said of the exit.

Trump was asked by the officers whether he plans to launch a comeback run for the White House in 2024 or for mayor of New York. He said it was an easy decision that would make them happy.

“If I catch COVID, it’s because of you,” Trump said as he posed for photos with police officers.

Trump planned to end the day in Florida, where he is providing commentary on a boxing match.
