FBI Deputy Director Andrew McCabe, criticized by President Donald Trump and other Republicans for alleged bias against him and in favor of his 2016 Democratic opponent Hillary Clinton, has stepped down, a source familiar with the matter said on Monday.
The deputy was eligible to retire in March, but with accumulated leave, he is able to step down earlier.
Trump has blamed McCabe for influencing the decision not to criminally charge Clinton for her use of a private email server.
In recent months, McCabe has been harshly criticised by congressional Republicans who challenge the FBI's rationale for opening the Russian Federation probe back in July 2016. "I will continue fighting on behalf of the American people to expose and eradicate corruption within the Federal Bureau of Investigation and Department of Justice - equal and fair treatment under the law is the cornerstone of American values, and must be upheld at all times", Gaetz added. His wife ran for a state Senate office in Virginia and received donations from former Virginia Gov. Terry McAuliffe, who has been linked to the Clintons for years.
Last month, Trump gave a push to McCabe, questioning reports that he would stay in the job until the spring: "90 days to go?!"
"The president was silent for a moment and then turned on McCabe, suggesting he ask his wife how it feels to be a loser", NBC News reports.
The White House was not involved in McCabe's decision, press secretary Sarah Huckabee Sanders told reporters Monday afternoon.
When asked on January 25 to confirm or deny the report, Sanders said: "The president and Andrew McCabe have had limited and pretty non-substantive conversations".
Special prosecutor and former FBI director Robert Mueller is now in charge of leading the investigation.
Trump has also said McCabe is "racing the clock to retire with full benefits".
