Sept. 23 (UPI) -- Would-be assassin Ryan Routh tried to stab himself with a pen after a jury on Tuesday found him guilty of trying to kill President Donald Trump last year. Upon hearing the verdict, Routh began stabbing his neck with a pen in the U.S. District of Southern Florida courtroom in Fort Pierce. Routh said he had a "prime opportunity" to shoot Trump but did not and rhetorically asked the jury, "Why was the trigger not pulled?" Routh represented himself during the 12-day trial and is a resident of Hawaii and a former Trump supporter, according to USA Today. He failed to convince the jury that he is "non-violent" and that federal prosecutors did not prove beyond a reasonable doubt that he intended to assassinate Trump.
