You are reaching so hard, your arm must hurt.
Are you really going to argue that Trump had an unprecedented mandate because he was a convicted felon under investigation?
That is not what he said. He referred to margin of victory and claimed we had never seen anything like it.
btw "Special Counsel Role: In 2017, Robert Mueller was appointed Special Counsel by Deputy Attorney General Rod Rosenstein, which is a position that does not require Senate confirmation."
The article that you cited from CFR.org states Trump as saying "America has given us an unprecedented and powerful mandate". That's the extent of the quote that was used, then went on a mission to use numbers to argue against an unprecedented and powerful mandate.
" He referred to margin of victory and claimed we had never seen anything like it."
When has a former President, a convicted felon and under special counsel investigation, been returned to office ?
Have you "seen anything like it" ?
btw, Aileen Cannon decided that Jack Smith was unlawfully appointed.
