Senator John Curtis, a Republican from Utah, has urged the Senate Judiciary Committee to investigate Donald Trump Jr. following reports that a Russian oligarch, Umar Kremlev, funded a lavish after-party for his wedding in the Bahamas. Curtis described the gift as "corruption" and stated his intent to address the issue. The after-party, which included a private island rental and a fireworks show, was held in May, and its costs were reportedly covered by Kremlev, who is the head of the International Boxing Association and has ties to Russian President Vladimir Putin.

In a letter to the committee, Curtis specifically requested a subpoena for Trump Jr. to examine his business dealings, relationships with foreign individuals and entities, and any benefits received where his connection to his father, then-President Donald Trump, might have been leveraged. The senator also highlighted concerns about Trump Jr.'s promotion of family-backed cryptocurrency ventures, international real estate deals involving foreign heads of state, and investments in defense contracting. He emphasized the need to determine if existing ethics laws apply and to identify reforms to prevent the presidency from being used for private enrichment.

Curtis extended his call for scrutiny to include Hunter Biden, son of former President Joe Biden, advocating for a single standard of accountability regardless of political affiliation. President Donald Trump defended Kremlev's involvement, stating that his son would repay the cost, and later claimed that his son had indeed repaid Kremlev. Bettina Trump, Donald Trump Jr.'s wife, confirmed on Instagram that Kremlev, whom she called a "dear friend," generously hosted two celebration nights after their wedding.

Curtis, who was elected to the Senate in 2024, has been critical of Trump in the past and vowed not to shy away from disagreeing with him. His call for an investigation into a sitting president's son, particularly from within his own party, marks a notable step. Other Republicans, like Sen. Thom Tillis, have also criticized the arrangement, calling it "beyond bad," while Senate Majority Leader John Thune expressed a need for more information before commenting.
