The timing of McCabe's ouster means he may lose out on a full pension after 20 years of working for the FBI. US President Donald Trump hailed the firing as a "great day for Democracy."
US Attorney General Jeff Sessions on Friday fired former FBI Deputy Director Andrew McCabe two days before the 20-year FBI veteran was set to retire.
US President Donald Trump had heavily criticized McCabe for what the president said was McCabe's bias against his administration.
What we know so far:
What were the reactions?
Trump wrote on Twitter: "Andrew McCabe FIRED, a great day for the hard working men and women of the FBI — A great day for Democracy." He added: "Sanctimonious James Comey was his boss and made McCabe look like a choirboy."
McCabe said his ouster was part of Trump's "ongoing war on the FBI" and the investigation into Russian meddling in the 2016 presidential election. He added: "This attack on my credibility is one part of a larger effort ... to taint the FBI, law enforcement and intelligence professionals more generally."
Trump's beef: Trump has accused McCabe of representing a broader FBI bias against his administration. He criticized McCabe in December after a media report found McCabe's wife had received political donations from a Democratic lawmaker in 2015 while she was running as a Democrat for a state Senate seat.
Trump's focus: Trump wrote on Twitter in December about McCabe's upcoming eligibility to retire with a full pension: "FBI Deputy Director Andrew McCabe is racing the clock to retire with full benefits. 90 days to go?!!!"
Who is Andrew McCabe? The 49-year-old lawyer joined the FBI in 1996. He was the bureau's top counterterrorism official during the Boston Marathon bombing in 2013. He became acting FBI director after Trump dismissed former FBI Director James Comey in May 2017.
