Less than two days after President Trump was elected, former President Barack Obama sat down with Trump for a 90-minute conversation in the Oval Office. During that meeting, Obama warned Trump that he should not hire Flynn as his national security adviser. Former Obama officials told
NBC in 2017 that Obama’s warning was centered on Flynn’s mismanagement issues and his temperament when he was head of the Defense Intelligence Agency under the Obama administration. Flynn was fired from that post in 2014.
While it wasn’t until after Flynn had already been hired, Trump was also warned by two different officials — whom he later fired — in early January that Flynn was under investigation.
