A possible Mueller target: the influence of foreign cash

George Nader, an "adviser to the United Arab Emirates with ties to current and former aides to President Trump, is cooperating with the special counsel ... and gave testimony last week to a grand jury," per the N.Y. Times.

Why it matters: "Mueller appears to be examining the influence of foreign money on Mr. Trump’s political activities and has asked witnesses about the possibility that ... Nader ... funneled money from the Emirates to the president’s political efforts."
