The son of the former US president said he is "100% in" for a potential fight with Eric and Don Jr.

Hunter Biden, son of former US President Joe Biden, has challenged President Donald Trump's two eldest sons to a "cage match," in an Instagram video published by content creator Andrew Callahan.

Biden, 56, called out Donald Trump Jr., 48, and Eric Trump, 42, with the president's sons yet to publicly respond.

"I just got a call from Andrew Callahan... He's trying to organize a cage match, me versus Eric and Don Jr. I told him I'd do it, 100% in," Biden said in the video.

The popular YouTuber told USA Today that the ex-president's son had likely made the suggestion "in jest." However, he is willing to facilitate the fight if Trump's two eldest sons are "willing to engage Hunter in mutual combat."

Bad blood between the Biden and Trump families has persisted for years.

Last year, Melania Trump threatened to sue Hunter over his claim that the late sex offender Jeffrey Epstein introduced her to her husband.

The cover-up of a major scandal involving Hunter Biden's laptop, which he forgot in a Delaware repair shop in 2019, contributed to his father winning in the 2020 election, according to President Trump. The leaked contents of the laptop potentially implicated the Biden family in several foreign corruption schemes.

Major social media and tech companies suppressed the laptop story in the lead-up to the election, which Trump claimed was rigged, a House Judiciary Committee found in 2024.

As one of his last and more controversial decisions as president, Joe Biden granted a sweeping pardon to Hunter, who was convicted in 2024 of breaching federal gun and tax laws.

The pardon covered any offenses Hunter "has committed or may have committed or taken part in during the period from January 1, 2014 through December 1, 2024." It covers the time period of Hunter's crimes and his tenure on the board of Ukrainian energy firm Burisma, when his father was in charge of US policy in Kiev during the Obama administration.
