President Donald Trump and former FBI Director James Comey had a contentious relationship well before last year’s election, starting with Comey’s public declaration in July that “no reasonable prosecutor” would charge Democratic candidate Hillary Clinton and her staff over their “extremely careless” handling of emails at the State Department.
Since the election, their conflict escalated over the FBI’s investigation into Russian meddling in the campaign—and into whether anyone close to Trump colluded with the Russians, an inquiry Trump has called a “witch hunt.”
Michael Flynn was Trump’s national security adviser for less than a month when forced to resign on Feb. 13 for misrepresenting the nature of a meeting with Russia's ambassador to the U.S. during the presidential transition.
