'What's happening?' GOP confused as Biden dons 'Trump 2024' hat in show of 9/11 unity

President Joe Biden wore a "Trump 2024" hat on Wednesday — and though it confused Republicans, he had a specific reason for doing so.

The president was at an event in Shanksville, Pennsylvania, to mark the anniversary of the Sept. 11 terrorist attacks. Shanksville was the site of the United Flight 93 crash, in which passengers revolted against hijackers trying to fly the plane into a government building in Washington, D.C.

Shanksville is in a small, conservative county where voters backed former President Donald Trump by a margin greater than 3 to 1, and many attendees were wearing Trump merchandise, including MAGA hats. According to Newsweek, White House officials said that in a show of nonpartisan solidarity and unity, Biden handed one of the attendees a Harris-Walz campaign hat, then took that man's "Trump 2024" hat and donned it himself, posing in a video and in a photo with children.

Republicans appeared either confused by the president's actions, or simply made fun of them.

"What's Happening?" posted Trump campaign manager Chris LaCivita.

The Trump War Room campaign account, meanwhile, posted, "BREAKING: Kamala did so bad in last night's debate, Joe Biden just put on a Trump hat."

Meanwhile, Benny Johnson, a right-wing influencer who was one of many singled out by the Department of Justice in their criminal charges against a pair of Russian state media officials who allegedly helped promote certain social media content to exacerbate U.S. political divisions, posted, "Photo of Joe Biden looking absolutely shook surrounded by Pennsylvania kids rocking Trump and MAGA gear. Zoom in. The shirts on these kids are incredible. Love this energy."
