The disclosure Tuesday of a James B. Comey memo saying that President Trump had asked him to shut down the FBI’s investigation of former national security advisor Michael Flynn followed months of intrigue.
Trump has frequently belittled investigations underway into Russian meddling in the presidential election. His comments, often on Twitter, have only heightened the suspicions of his detractors about Russia’s ties to Flynn and other senior Trump campaign advisors.
Last week, Trump fired Comey. Democrats have accused the president of trying to obstruct the inquiry by ousting the man who had been heading it. The existence of a memo documenting private conversation between Comey and Trump, first reported Tuesday by the New York Times, has set off widespread speculation that Trump could now be vulnerable to impeachment.
Here’s a timeline on the drama that has unfolded since Trump won the Nov. 8 election:
