This incredible possibility emerged on Thursday when Hunter Biden, son of former Democratic President Joe Biden, challenged the eldest sons of Republican President Donald Trump, Donald Jr. and Eric, to a fight. Biden said he was contacted by social media commentator Andrew Callaghan, who told him he was organizing the match. "I told him I agree. I'm 100 percent in if he can pull it off. And if he can't, I'm still coming," he said in a video shared on Instagram. It is unclear whether and when this match will actually take place. The White House is planning a similar event, but with real UFC fighters, on June 14, as part of a series of events marking the 250th anniversary of the independence of the United States. Biden became president after defeating Trump in the 2020 election, which the Republican still falsely claims was the result of widespread electoral fraud. The fight threat between their sons recalls the proposed 2023 cage match between tech billionaires Mark Zuckerberg and Elon Musk, although that event never took place. Earlier eras of American politics witnessed bloody political showdowns, notably the 1804 duel between Vice President Aaron Burr and former Treasury Secretary Alexander Hamilton, which ended in Hamilton's death and effectively ended Burr's political career.
