President Joe Biden caused a stir online after being photographed wearing a “Trump 2024” baseball cap during a 9/11 Memorial event in Shanksville, Pennsylvania. The unexpected moment came after Biden accepted a dare to put on former President Donald Trump’s signature red cap while attending the ceremony alongside Vice President Kamala Harris. The image quickly went viral on social media platform X (formerly Twitter), prompting a flood of reactions, with many users humorously suggesting that Biden is secretly a Trump supporter or dislikes his VP, Kamala Harris.

Some political commentators on social media found the photograph amusing, with many calling it “the most iconic image” of Biden’s presidency. The Trump campaign wasted no time in responding to the viral moment, cheekily claiming that Biden had finally endorsed Trump’s 2024 bid for the White House. However, the White House was quick to clarify, stating that Biden’s decision to wear the cap was a gesture of bipartisan unity in a time of national remembrance.

Earlier in the day, Kamala Harris and Donald Trump stood together in New York City at a separate 9/11 event, where the two rivals were seen shaking hands. Trump later described the handshake as “polite,” although he declined to reveal the contents of their brief exchange.

This symbolic act of unity came just hours after Harris and Trump faced off in their first debate of the 2024 presidential race in Philadelphia. Despite Trump declaring himself the winner, post-debate polls indicated that most viewers believed Harris had the upper hand in the exchange. ABC News, which hosted the debate, reported that 67.1 million viewers tuned in—significantly more than the audience for Trump’s 2020 debate with Biden.

Though the Harris campaign has expressed interest in a second debate, Trump has yet to commit. For now, both candidates are energized by the debate’s massive viewership, and neither appears ready to step back from the race. As the 2024 election looms, this viral moment has only added fuel to an already charged political atmosphere.
