Initially delighted by the prospect ("A threefer!") of being rid of criticism ("So unfair") from retiring Washington Post editorial cartoonist Tom Toles, getting to name his replacement with "Some Trump-friendlier guy" ("How about Dilbert? He still likes me, right?"), and, as a bonus, sticking it to the paper's owner and long-time enemy and for-real billionaire Jeff Bezos, President Trump flew into a characteristic rage when informed that doing so was not within his presidential powers.
Aides were finally able to calm the president by assuring him that nobody but Washington Post readers read the Washington Post and that, yes, people are saying that Dilbert likes him as much as ever, so far as they know.
