On Twitter, Trump pushed the baseless theory that Scarborough killed Lori Kaye Klausutis, 28, who was found dead in Scarborough's congressional office in Fort Walton Beach, Fla., in July 2001.
"There has been a constant barrage of falsehoods, half-truths innuendo and conspiracy theories since the day she died," widower Timothy J. Klausutis wrote last week to Twitter CEO Jack Dorsey. "... Because of this, I have struggled to move forward with my life."
He went on to ask Dorsey: "My request is simple: Please delete these tweets,"
Despite the plea, Twitter has not removed the tweet advancing the false conspiracy theory about the death of Klausutis' wife, who had an undiagnosed heart condition, passed out and hit her head on her desk when she fell. Dorsey never directly replied to the widower's letter.
