A member of Donald Trump’s political party has issued a rare call for a congressional investigation into the foreign dealings of the United States president’s eldest son.
US Senator John Curtis, a Republican from the state of Utah, on Tuesday said “questions have arisen” about Donald Trump Jr’s relationships with foreign business figures and acceptance of “significant gifts”, alleging he may have personally benefited from his relationship with the president.

In a letter to the Republican and Democratic leaders of the US Senate Judiciary Committee, Curtis referenced a ProPublica report that found Trump Jr’s Bahamian wedding party in May was funded by a Russian oligarch.
“These reports raise legitimate questions about foreign access to members of a sitting president’s family and whether such relationships can create actual or perceived expectations of favorable treatment,” Curtis wrote. “They also may create expectations of a returned favor that would not be in the best interests of the American people or our allies, and could even create national security vulnerabilities.”
The letter comes as a small but slowly growing number of Republicans have spoken out against Trump, who has largely avoided criticism from members of his own party. But record-low approval ratings sparked by the war in Iran and concerns over the cost of living in the US have forced some Republicans to reconsider that support as they face growing prospects of major losses in the congressional midterm elections.
If Democrats retake one, or both, chambers of the US Congress in November, investigations into Trump, including his family’s dealings, are likely. But those probes are less likely under Republicans wary of the president’s wrath.
A spokesperson for the Senate Judiciary Committee, which is under Republican control, told the Associated Press that it had received Curtis’s letter but did not say whether there would be an investigation.
Trump vs Biden
Curtis, who isn’t up for re-election until 2030, also called on the chamber’s panel to subpoena Trump Jr, as well as the son of former US President Joe Biden, a Democrat.
“The country should not have to accept one standard for the family of a Republican president and another for the family of a Democratic president,” Curtis wrote, referencing the scrutiny and investigation Biden’s son Hunter faced from Republicans.
Hunter Biden responded to Curtis’s letter in a post on social media, calling for the Senate committee to “bring it on” as he vehemently denied any foreign business dealings while his father was president.
“I’ll sit next to Don Jr. and testify any time, any place,” Biden wrote on X as he called for the president’s youngest son, Eric, and son-in-law, Jared Kushner, who serves as a US envoy, to testify as well. “No need for a subpoena. Let’s all do it tomorrow.”
After the ProPublica report, Trump Jr and his wife, Bettina, released a joint statement on social media saying the Russian oligarch, Umar Kremlev, was a “dear friend” who “very generously hosted two incredible nights of celebrations for us AFTER our wedding”.
The president, who did not attend the wedding, said his son had reimbursed Kremlev.
“It’s totally allowed, and a lot of people give parties and things like that — but it’s totally allowed,” Trump said. “But as I understand it, he paid him back. He didn’t want it.”
US Senator Dick Durbin, the ranking member on the Senate Judiciary Committee, said that while Biden’s son “has already given a sworn deposition to Congress”, Trump Jr “has not”.
“For the committee to ignore this matter is to run the risk of being complicit in a coverup,” Durbin said. “I will join in supporting Senator Curtis’ request of the Senate Judiciary Committee.”
Curtis’s office did not immediately reply when asked by Al Jazeera what prompted the senator’s letter and whether any fellow Republicans have indicated if they would support an investigation into the president’s family.
