Attorney General is looking at a recommendation to fire McCabe, people briefed on the matter told The New York Times for a report published Wednesday.

The recommendation comes amid an internal review looking into a choice McCabe made in 2016 to allow agency officials to speak with reporters about a Clinton Foundation investigation.

According to the Times, a report from the Justice Department's inspector general regarding the internal review triggered an FBI disciplinary process that recommended McCabe's firing. Sessions now has to decide whether to accept the recommendation, according to the Times.

McCabe's retirement is set to go into effect Sunday and his firing could jeopardize his pension as a 21-year veteran of the bureau, according to the report. 

A spokeswoman for the Justice Department told the Times that the department "follows a prescribed process by which an employee may be terminated."
