President Donald Trump's campaign manager is calling for the firing of Attorney General Jeff Sessions.

"Time to fire Sessions End the Mueller investigation," Brad Parscale wrote in a Tuesday tweet.

Time to fire Sessions



End the Mueller investigation



You can’t obstruct something that was phony against you



The IG report gives @realDonaldTrump the truth to end it all. — Brad Parscale (@parscale) June 19, 2018

Parscale's tweet refers to the Department of Justice Inspector General's report that indicated former FBI Director James Comey "deviated" standard procedures in handling the probe into ex-Democratic presidential candidate Hillary Clinton, the Department of Justice's Inspector General found. The findings come amid an investigation into possible Russian involvement in the 2016 presidential election and allegations of collusion with the Trump campaign.

Sessions, a former Alabama Senator, has recused himself from the investigation, drawing the ire of Trump.

Parscale also blasted comments that then-Senator Sessions' backing during the campaign helped Trump win the White House.
