A top fundraiser for President Donald Trump received millions of dollars from a political adviser to the United Arab Emirates last April, just weeks before he began handing out a series of large political donations to US lawmakers considering legislation targeting Qatar, the UAE’s chief rival in the Persian Gulf, an Associated Press investigation has found. George Nader, an adviser to the UAE who is now a witness in the US special counsel investigation into foreign meddling in American politics, wired Dollar 2.5 million to the Trump fundraiser, Elliott Broidy, through a company in Canada, according to two people who spoke on the condition of anonymity because of the sensitivity of the matter. They said Nader paid the money to Broidy to bankroll an effort to persuade the US to take a hard line against Qatar, a long-time American ally but now a bitter adversary of the UAE.
