And no, despite the subject line, this is not an article about zzfart.
Federal employees just don't get fired 24 hours before retirement. It doesn't happen. The fact that it did to McCabe is a clear indication of the extent to which Donald Trump despises him. It sounds like the President had good reasons to, though. Perhaps McCabe will finally be the Establishment official who gets prosecuted. It wouldn't surprise me.

You’re Fired: Deputy FBI Director McCabe Is Officially Out Before Retirement

It’s over. Former Deputy Director of the FBI Andrew McCabe has been fired from the bureau. The announcement occurred a little after 10 P.M. the move comes around two days prior to McCabe receiving his hefty pension package. That is now in doubt, though The Washington Post said McCabe could file a lawsuit to receive full benefits. He spoke with FBI officials for four hours this week to ensure he wasn’t terminated before his pre-determined retirement (via WaPo):

Attorney General Jeff Sessions late Friday night fired former FBI Deputy Director Andrew McCabe, a little more than 24 hours before McCabe was set to retire.
Sessions announced the decision in a statement just before 10 p.m., noting that both the Justice Department Inspector General and the FBI office that handles discipline had found “that Mr. McCabe had made an unauthorized disclosure to the news media and lacked candor — including under oath — on multiple occasions.”
He said based on those findings and the recommendation of the department’s senior career official, “I have terminated the employment of Andrew McCabe effective immediately.”
The move will likely cost McCabe a significant portion of his retirement benefits, though it is possible he could bring a legal challenge. McCabe has been fighting vigorously to keep his job, and on Thursday, he spent nearly four hours inside the Justice Department pleading his case.

McCabe was cited for improperly disclosing the friction between the Department of Justice and the FBI over the investigation into the Clinton Foundation to The Wall Street Journal, and for misleading investigators when questioned about it in a DOJ inspector general report. Due to this revelation, the FBI’s Office of Professional Responsibility recommended his termination.
