"The fix was in from Donald Trump when he tweeted 90 days ago his threat about McCabe’s pension. This is a complete disgrace. Sure to exacerbate concerns among “the generals” about his conduct in office," Wallace tweeted.

Sessions's decision came after an "extensive and fair" internal probe into McCabe's alleged misconduct at the bureau, which included his handling of the investigation into Clinton's server use.

Trump praised the deputy director's removal as "a great day for democracy." In December, Trump said that McCabe was "racing the clock" to retire with benefits. His firing on Friday came two days before McCabe's pension would kick in.

Wallace, who hosts MSNBC's “Deadline: White House,” asked on air this week how Trump could be so much of a "bleep-hole" for pressuring Sessions to fire the embattled FBI official, according to Mediaite.
