It seems the political arena might soon witness an unconventional showdown, as Hunter Biden, son of former President Joe Biden, hints at a possible cage fight with the eldest sons of Donald Trump.

During a promotional stint for an upcoming tour with renowned journalist Andrew Callaghan, Hunter disclosed the possibility of stepping into the ring with Donald Trump Jr. and Eric Trump.

“Andrew has invited me to join the Channel 5 Carnival Tour later this month,” Biden shared in a social media video. “Our journey kicks off in Phoenix, moves to San Diego, and concludes in Albuquerque.”

Hunter elaborated, “Andrew is trying to set up a cage match between me, Don Jr., and Eric. I’ve agreed to participate, no question, if he makes it happen. Even if not, I’m still committed to the tour.”

The Daily Mail has reached out to representatives of the Trump Organization for their comments on this potential clash.

At 56 years old, Hunter stands approximately 6 feet tall. In contrast, Don Jr., 48, is roughly the same height, while Eric, 42, towers at about 6 feet 4 inches. All three maintain active lifestyles: Hunter has embraced a healthier regimen following his recovery from substance issues, Don Jr. is a fitness enthusiast with a penchant for weightlifting, and Eric regularly hits the golf course, emulating his father’s passion for the sport.

Hunter’s announcement comes as the Daily Mail has revealed he is now $17 million in debt and living overseas.

The disclosure came in a new legal filing submitted by his attorney Barry Coburn on April 6, in Washington DC, where the first son is being sued by his former attorneys at Winston & Strawn.

The court filing bluntly states ‘Mr Biden lives abroad’, and argues that the former First Son ‘cannot afford’ to pay off his outstanding legal fees.

The law firm defended Hunter, 56, in his tax and gun crimes cases, as well as other legal battles, but claims he failed to pay bills ‘substantially in excess of $50,000’.

On a podcast appearance last year Hunter himself claimed he was in ‘$17 million of debt.’

Coburn declined to comment to the Daily Mail, and did not specify where in the world Hunter, 56, now lives – but it’s not America.

However, last year Hunter was spotted spending time in South Africa, the birthplace of his wife Melissa, 39, the mother of his youngest child.

The couple was seen on a trip to Cape Town in May 2025, prompting President Trump to revoke his Secret Service detail over the cost of foreign travel.

The President’s eldest son and namesake regularly pokes fun at Hunter’s well-known struggles with drug addiction, while also rejecting any comparisons between the two.

When Business Insider likened Hunter’s controversial work with a Ukrainian gas giant to his own business dealings, Don Jr. lashed out in a furious post on X.

‘The difference between me and Hunter Biden?’ Don Jr. asked, rhetorically. ‘I’ve been a businessman and serial investor my entire adult life.

‘[Hunter] became a ‘businessman’ after his dad got elected,’ Don Jr. continued. ‘I joined a Venture Capital Firm that invests in private American companies – Nothing to do with the government. He sat on foreign boards and was peddling influence to the highest bidder to change government policy.

‘Oh,’ Don Jr. added, shepherding the conversation back to Hunter’s drug problems, ‘he’s also a felon crackhead and I’m not. Thanks for playing, guys!’

But both Don Jr. and Eric Trump have faced accusations of corruption over their business dealings, both at home and abroad. 

As The Wall Street Journal recently revealed, the two poured money into Powerus, a Florida-based defense start-up competing for Pentagon drone contracts. The company, formed in 2025, is competing for a slice of the Pentagon’s $1.1 billion Drone Dominance initiative and is merging with a publicly traded golf company to list on the NASDAQ.

The Pentagon’s push to acquire its own drone fleet has been thrown into sharp focus by Iran’s battlefield deployment of Shahed drones costing approximately $25,000 per unit, as the US burns through missile stockpiles priced at up to $13 million each.

The venture comes after the President declared foreign-made drones a national security threat in December.

The controversy is the latest in a string of deals the Trump brothers have struck in the booming US drone sector, as the administration intensifies its focus on domestic manufacturing amid the war with Iran.

Eric invested in a merger between Israeli drone firm XTEND and a Florida-based construction company to bring the firm to public markets in February.

Last year, Unusual Machines, another Florida-based drone firm, appointed Don Jr. to its board.

Unusual Machines has won money from the Pentagon, including a contract for it to manufacture 3,500 drone motors and other parts. Furthermore, Don Jr. purchased more than 331,000 shares of Unusual Machines, worth around $5.5 million, the Financial Times reported.

Chinese-made drones, particularly from tech giant DJI, have accounted for the majority of commercial drone sales in the US for the past decade. The firm now faces a questionable future in US markets, given the administration’s latest ban on foreign-made drones.

And then there is Don Jr.’s connection to the budding prediction markets, which are regulated by his father’s Commodity Futures Trading Commission.

The emerging industry’s trading platforms work like online sportsbooks by offering futures contracts at prices and returns that fluctuate like betting odds (i.e. underdogs pay off better than favorites). Customers are given binary choices (‘yes or no’ or ‘one or the other’) on any number of positions, from gas prices to the next Pope and, of course, sports: Will the Celtics win this year’s NBA title? etc.

Platforms like Kalshi and Polymarket made news during the 2024 US Presidential race by using customers’ wagers to accurately forecast Donald Sr.’s electoral victory over Kamala Harris. Since then, the industry has faced cease-and-desist orders in several states as platforms have taken billions in bets on everything from March Madness to the Masters.

Crucially, these websites consider themselves to be ‘exchanges’ rather than ‘sportsbooks.’ As a result, they face fewer taxes and are more widely available because they’re not being prohibited, or even regulated, by individual states. Rather, prediction markets are under the federal jurisdiction of the Commodity Futures Trading Commission (CFTC) — something Nevada state senator Dina Titus described as a ‘backdoor way’ to legalizing sports gambling without necessary safeguards.

Don Jr. not only works as a strategic advisor to Kalshi, but also holds a similar role as well as a seat on the advisory board for Polymarket.
