Deputy Attorney General Rod Rosenstein is expected to leave his role at the Justice Department next month.
A senior DOJ official has told multiple media outlets that Rosenstein will step down by mid-March.
He is leaving his post after he headed Robert Mueller's probe into Russian meddling in the 2016 election and was a frequent target of President Trump's twitter rants.
The president has also accused him of being part of an 'illegal and treasonous' plot to secretly record him and get him removed from office.
The senior official who told CNN about his impending departure said the timing was nothing to do with former acting FBI director Andrew McCabe's claims that Rosenstein wanted to remove Trump in 2017 after he fired James Comey.

On Sunday, Trump tweeted 'treason' alongside a quote from Fox News host Sean Hannity that said: 'The biggest abuse of power and corruption scandal in our history, and it’s much worse than we thought. Andrew McCabe (FBI) admitted to plotting a coup (government overthrow) when he was serving in the FBI, before he was fired for lying & leaking.'
According to McCabe, in a lengthy interview that aired Sunday on CBS's '60 Minutes,' Rosenstein brought up the possibility of invoking the 25th Amendment of the US Constitution, which provides for the removal of a sitting president for incapacity.
'Rod raised the issue and discussed it with me in the context of thinking about how many other cabinet officials might support such an effort,' said McCabe, who has a book coming out, 'The Threat.'
Trump slammed their reported discussions about invoking the Constitution to remove him as part of an 'illegal and treasonous' push against him.
McCabe and Rosenstein 'look like they were planning a very illegal act, and got caught.....,' Trump said in a series of tweets.
'This was the illegal and treasonous 'insurance policy' in full action!'
Rosenstein, who became deputy attorney general at the start of Trump's tenure, long planned to only serve two years in the Number Two position at Justice, NBC News reported in
