Does he need a reason? I thought appointees "serve at the pleasure of the President".

Yep,
I had trouble understanding true born southerners with their accents when I moved south. It was like learning a foreign language.

I installed a speech-to-text app on my phone since I disliked trying to use the tiny keyboard but then had to keep going back and correcting words. I was telling a friend about it in a text message when I noticed "Texas accent" had been interpreted as "Text accident". I figured that was pretty much the same thing.

I often wonder why northerners talk so fast, it's like they're being charged by the minute for talking.

Sometimes they should be.
