OH NO! He has memos!

"Andrew McCabe, the onetime FBI deputy director long scorned by President Donald Trump and just fired by the attorney general, kept personal memos detailing interactions with the president that have been provided to the special counsel’s office and are similar to the notes compiled by dismissed FBI chief James Comey...."

If I were questioning him, I'd ask if he kept 'personal memos detailing his interactions with James Comey'. If he didn't, then I'd suggest that like James Comey and former UN Ambassador Samantha Power before him, he's just covering his own ass.

Answer me this question: Why would someone near the pinnacle of his career suddenly choose to (very) early retire (at age 50!) if he weren't a rat deserting a sinking ship?
