“During the 2016 Republican primaries, Grenell warned his Twitter followers about Donald Trump, described Trump as “unserious” and “dangerous”. “Trump is dangerous. Wake up. He’s reckless,” Grenell tweeted. Grenell deleted all of his negative tweets about Trump after Trump became the Republican nominee. Grenell then began praising Trump repeatedly on Fox News and on Twitter.”

Grenell was one of Trump’s best hires. One of the very few who was competent, and didn’t turn against Trump the first opportunity he got.
Not sure I trust Wikipedia. Grenell was well liked at the State Dept. Maybe he didn’t take Trump seriously when he was running many didn’t. But, he has been loyal to Trump and could have cut abd run during J6 like everyone else.
