Hunter Biden says Congress can seat him next to Donald Trump Jr. and put them both under oath.
Former President Joe Biden’s son issued the challenge Tuesday after Sen. John Curtis (R-UT) pushed the Senate Judiciary Committee to examine business ties around both presidential families and seek testimony from the two sons.
“Sen. Curtis of Utah has suggested that Don Jr. and I should testify before Congress,” Hunter Biden wrote on X. “I say bring it on. I’ve already given more than seven hours of sworn testimony. More than three dozen witnesses testified across two chambers.”
Hunter Biden cast himself as already investigated at length and denied doing foreign business while his father was in the White House.
“I had no foreign business dealings while my father was president. None. I painted paintings, and I still do,” he wrote. “I’ll sit next to Don Jr. and testify any time, any place.”

Curtis put the two political families into one ethics fight, asking Judiciary Committee Chair Chuck Grassley (R-IA) and ranking member Dick Durbin (D-IL) to look at whether presidents’ relatives have been leveraged for money, access or favorable treatment.
In the letter, Curtis warned that reports involving foreign interests and presidents’ sons raised questions about access to sitting presidents’ families and the expectations those relationships might create.
For Hunter Biden, Curtis cited “substantial business with foreign entities, including interests in China and Ukraine, while his father held or sought public office.”

For Trump Jr., Curtis pointed to ProPublica reporting that Russian oligarch Umar Kremlev covered a large share of the bill for a three-day post-wedding celebration in the Bahamas.
Curtis also tied the Kremlev gift to Trump Jr.’s promotion of family-backed cryptocurrency ventures, international real estate pursuits involving foreign heads of state and reported defense-contracting investments.
Trump Jr.’s ties to prediction-market platforms were also part of Curtis’ request because those platforms rely on favorable federal decisions under consideration by the Commodity Futures Trading Commission.
The senator wants both sons questioned about past business activity, foreign ties and gifts.
“Americans deserve confidence that public institutions serve them — not presidents, political parties, wealthy interests, or members of powerful families,” Curtis wrote. “Congress has an obligation to pursue credible concerns wherever they lead and without regard to party.”
Curtis had already criticized the Bahamas wedding event publicly before sending the letter.
“A Russian oligarch paid for a lavish wedding after-party for Donald Trump Jr., which to me just stinks. It’s corruption. I don’t like it,” Curtis said Friday in a social media video.
By Tuesday, he was urging Republicans not to abandon a tool they had used repeatedly on the Biden family.
Republicans “nearly wore out the subpoena machine investigating Hunter Biden’s foreign relationships,” Curtis wrote on social media, adding that they “should not unplug it now.”
Grassley, whose committee would decide what to do with the request, told reporters hours later that he had not yet gone through the letter.
“I can’t answer that question for you, or him, or anybody else because I just told a journalist downstairs I wasn’t going to answer the question until I read the letter,” Grassley said.
When asked why he had not read it, Grassley answered, “I just got to town.”
Some Republicans on the Judiciary Committee sounded more willing to entertain Curtis’ push.
Sen. John Cornyn (R-TX), a senior member of the panel, gave his answer after a GOP leadership meeting.
“I’m with Sen. Curtis,” Cornyn remarked. “I would support Sen. Curtis’s request.”
Sen. Thom Tillis (R-NC) said Trump Jr.’s acceptance of generous gifts from a Russian oligarch raised serious questions, while declining to commit to a subpoena.
Tillis said he would “have no problem” with the committee taking up the matter after the election.
“If I were Donald Trump Jr., I’d be offering this up immediately,” Tillis said. “Just lay it out there. How on earth did this happen? Because on its face, it looks pretty dumb.”
Tillis also warned that if the House flips next year, “there’s going to be an investigation one way or the other.”
Sen. Bill Cassidy (R-LA), who is retiring at the end of his term, called the gifts “really bad” during an appearance on CBS News’s “Face the Nation.”
“Anytime someone gives you a $250,000 gift and they have strong ties to the Kremlin, that’s wrong,” Cassidy said.
Cassidy noted that Trump Jr.’s closeness to the Russian president also created poor political optics for the White House.
Durbin told the Daily Caller he supported Curtis’ request for a committee investigation into Trump Jr.
“It was a great letter, I support it,” Durbin said. “I think we ought to have an investigation into Donald Trump Jr.”
Durbin said the committee risked appearing complicit if it ignored the matter.
“For the committee to ignore this matter is to run the risk of being complicit in a cover-up,” he said. “I will join in supporting Sen. Curtis’s request of the Senate Judiciary Committee.”
Sen. Chris Coons (D-DE) credited Curtis for seeking scrutiny of possible corruption involving Trump Jr.
“No one is above the law,” Coons said. “I’m glad to see Republican colleagues like John increasingly refusing to turn a blind eye to corruption from this administration and the Trump family. The American people want an equal standard.”
President Trump defended his son Friday after Bettina Anderson confirmed that Kremlev hosted some of her and Trump Jr.’s post-wedding festivities on a private island in the Bahamas as “an extraordinarily generous wedding gift.”
President Trump on Friday defended his son's wedding being partially paid for by a Russian oligarch, but also said he heard Don Jr. "paid him back."

Trump said he had heard Trump Jr. “paid him back.”
“That’s very common,” Trump said, adding, “I’ve given wedding parties for numerous people. They get married, I give them a party.”
