Some people think so:

The sun had not been up for an hour when the president of the United States, in his ninth tweet of the day, said MSNBC anchor Joe Scarborough might be a murderer.

His exact words?

“When will they open a Cold Case on the Psycho Joe Scarborough matter in Florida. Did he get away with murder? Some people think so. Why did he leave Congress so quietly and quickly? Isn’t it obvious? What’s happening now? A total nut job!”

This isn’t random person making noise on Twitter, this is a head of state, a head of an all-too-powerful nuclear-armed state.

Many of the 18,000 false and misleading claims in our Trump database feature overheated rhetoric. Few of them rise to these vicious heights.

…

Trump first lobbed this conspiratorial charge at Scarborough in November 2017. The president is referring to the 2001 death of Lori Klausutis, a 28-year-old aide who worked for Scarborough when he was a Republican member of Congress representing Florida’s 1st Congressional District.

The circumstances of Klausutis’s death have spawned conspiracy theories, but authorities never suspected foul play. Her death is not an unsolved mystery or a cold case waiting for answers. Klausutis’s death on July 20, 2001, was ruled accidental and the police concluded there was no reason to further investigate. A police investigator told The Post in 2017 that authorities had left “no stone unturned.”

The Post gives it 4 Pinocchios and wishes it had more to give. The White House has refused to comment.
