Scott Pelley Fired From CBS After His Showdown With Leadership (youtube.com)
Seems the company put a new leader in, who is not a journalist, and doesn't have qualifications and maybe not ethics, if the resignation letter is to be believed.
They note that a lot of this CBS mess has been since David Ellison took over Paramount (parent company of CBS) months ago.
Trump has made blunt, disparaging comments about Pelley in an interview.
Some commenters noted that Pelley gets to leave with his integrity.
