Comey, who was fired by Donald Trump within four months of him taking over the Oval Office, has been an outspoken critic of the president and has called on Americans to deliver a landslide victory for the Democratic nominee in 2020.
"All of us should use every breath we have to make sure the lies stop on January 20, 2021," Comey told a New York City audience last December. The former FBI director added during an MSNBC appearance that Democrats "have to win."
Earlier this year, Comey gave $2,700 to the presidential campaign of Sen. Amy Klobuchar (D., Minn.), who was in his class at the University of Chicago Law School. The money to Klobuchar's campaign came on the heels of $2,700 that Comey gave to both Jennifer Wexton (D., Va.) and Abigail Spanberger (D., Va.) during last year's midterm elections. Comey also canvassed for Wexton in her Virginia congressional district on Election Day.
Comey, a former Republican, previously donated to John McCain's 2008 presidential campaign and Mitt Romney's 2012 campaign before switching his monetary support to Democrats during the 2018 elections, filings show.
