Tom Barrack, the longtime friend of President Trump and the chairman of his inaugural, is the subject of a federal probe into influence peddling by foreign governments, the New York Times reports.

“Investigators have looked in particular at whether Mr. Barrack or others violated the law requiring people who try to influence American policy or opinion at the direction of foreign governments or entities to disclose their activities to the Justice Department.”

“The inquiry had proceeded far enough last month that Mr. Barrack, who played an influential role in the campaign and acts as an outside adviser to the White House, was interviewed, at his request, by prosecutors in the public integrity unit of the United States attorney’s office in Brooklyn.”
