Sounds like WaPo's spin on this is fake news. Seems more like he was let go as part of the cost-cutting that's going on in news rooms all over the country:

Burris told the Post-Gazette that Rogers was offered a deal in which he would be an independent contractor, producing two op-ed-page cartoons a week and his weekly strip.
“We tried hard to find a middle way, an accommodation to keep him the paper,” Burris said. He also said, “For an in-house staff cartoonist, editing is part of it. Rob’s view was, ‘Take it or leave it.’ ”
Rather, it looks like folks are working pretty hard to try to make this story something that it's probably not:

“It doesn’t take much to connect the dots between the absence of Rob’s left-leaning cartoons and the recent arrival of a Trump-supporting editorial page editor,” the American Association of Editorial Cartoonists said in a statement. “The editorial pages are a public forum, not a members-only private resort in Florida.”
Sounds like what a lot of opinion - writers at WaPo and elsewhere are doing" connecting the dots with their imaginations when there aren't enough facts to do so.
