Pompeo no brake on Trump

Even a Twitter-holic such as Donald Trump will no doubt be aware that firing someone by tweeting his dismissal will be embarrassing for the person ousted from his job. And yet he did it.

Even if the US Secretary of State Rex Tillerson knew his days in office were numbered, it was humiliating for him to lose his job in such a way, especially since he was on an official trip overseas.

To some extent, Trump was probably repaying the embarrassment caused him by his top diplomat, since Tillerson was vocally at odds with him on many issues.
