The tweeter-in-chief has done it again.
President Trump's tweets almost always drive the daily news cycle, and his dismissal of Rex Tillerson via Twitter is merely the most recent time he's used the social media platform for major announcements about his administration.
The latest example came on Tuesday, when Trump took to Twitter to announce that he was replacing his secretary of state with his current CIA director, Mike Pompeo.
There are differing accounts about when Tillerson found out about his dismissal. Chief of Staff John Kelly spoke twice with Tillerson in recent days, and one White House official said Tillerson's status was "clear on Friday."
But the State Department said the secretary didn't know about the final decision until the president's tweet.
Reince Priebus and John Kelly
Last summer, after several days of upheaval that included the resignation of Sean Spicer and the grandiosity of Anthony Scaramucci, Trump announced via Twitter he was replacing then-Chief of Staff Priebus with then-Homeland Security Secretary Kelly.
The transgender ban
Last July, Trump announced his decision to ban transgender troops, in the span of three tweets.
The president had made his decision the day before and told Defense Secretary James Mattis — who was on vacation at the time — about it. Trump then used social media to announce it, leaving his White House and the Pentagon scrambling. The announcement caught the Pentagon by surprise, according to officials.
Honorable mention: James Comey
When then-FBI Director James Comey found out he'd been fired, it wasn't via Twitter. But it wasn't directly, either: It was through TV news reports.
Comey was in California, speaking with FBI agents, when the news came through.
He reportedly made a joke and carried on, but received confirmation when he called back to headquarters.
About a month later, the president did use Twitter for a related topic, though: announcing Comey's replacement.
