Joe Biden endorses Donald Trump

Answer
During a visit to a fire station in Shanksville, Pennsylvania, to commemorate the 23rd anniversary of the 9/11 attacks, President Joe Biden briefly wore a red "Trump 2024" hat as a gesture of bipartisan unity. The lighthearted moment unfolded when Biden engaged in a cordial conversation with a Trump supporter, who jokingly called him an "old fart." After Biden offered the man a cap bearing the presidential seal, which he signed, the supporter suggested that Biden wear his Trump hat. With playful hesitation, Biden obliged, prompting cheers from the crowd. The White House later clarified that the president's actions aimed to reinforce the theme of unity for the solemn occasion, highlighting the importance of restoring the bipartisan spirit that emerged in the aftermath of 9/11. This rare interaction between Biden and a predominantly Trump-supporting crowd stood out in an otherwise contentious political landscape.
