Donald Trump Jr and his wife, Bettina, confirmed on Monday that a Russian oligarch close to Vladimir Putin partially paid for the couple’s wedding celebrations in May, following a ProPublica report revealing Umar Kremlev spent hundreds of thousands of dollars on the events.

Trump Jr, the US president’s eldest child, married the Palm Beach socialite in a lavish three-day celebration across two exclusive private islands in May.

Citing records and interviews with three anonymous sources familiar with the event, ProPublica reported that Kremlev, a member of the Russian president’s circle, footed the bill to rent one of the islands where a reception was held and where guests slept, along with other large expenses, including a huge firework show.
