Fresno State University said they will fully cooperate with any federal investigation after a professor posted a series of Twitter messages calling for President Trump to be hanged and for Republicans to be executed.

“To save American democracy, Trump must hang,” Professor Lars Maischak wrote on his Twitter account in February. “The sooner and the higher, the better.”

“Has anyone started soliciting money and design drafts for a monument honoring the Trump assassin, yet?” the professor asked in an earlier tweet. 

Maischak, who is a history lecturer, also went after Republicans – tweeting, “Justice = The execution of two Republicans for each deported immigrant.”
