“The president did not fire him. He did not ask for his resignation,” Kelly, a retired Marine Corps general, said in an interview. “The president has clearly forgotten how it actually happened or is confused. The president tweeted a very positive tweet about Jim until he started to see on Fox News their interpretation of his letter. Then he got nasty. Jim Mattis is a honorable man.”

Mattis tendered his resignation in 2018, citing his disagreement with Trump’s decision to pull U.S. forces out of Syria.
