Trump transition team, including Mike Pence, was well aware Michael Flynn was under federal investigation at time he was hired at National Security Advisor.
Michael T. Flynn told President Trump’s transition team weeks before the inauguration that he was under federal investigation for secretly working as a paid lobbyist for Turkey during the campaign, according to two people familiar with the case.
Despite this warning, which came about a month after the Justice Department notified Mr. Flynn of the inquiry, Mr. Trump made Mr. Flynn his national security adviser. The job gave Mr. Flynn access to the president and nearly every secret held by American intelligence agencies. More from the New York Times here.
