The man who attempted to assassinate Donald Trump at a Florida golf course last year tried to stab himself in the neck with a pen shortly after being found guilty of all counts on Tuesday.

Officers quickly swarmed him and dragged him out of the courtroom.

The jury of five men and seven women found Ryan Routh guilty on all counts that he was facing after about two hours of deliberation.

The jurors were on their way out of the courtroom after the verdict was announced when Routh grabbed a pen off a desk and tried to stab himself in the neck.

As marshals were dragging him from the courtroom, Routh's daughter Sara Routh began screaming. She continued screaming as her father was taken from the courtroom, saying the case against him was rigged. She went outside the courthouse, where she and her brother Adam Routh waited by a guard gate for their father to be driven away.

Back inside the courtroom, Routh was brought back before the judge. He was no longer wearing a jacket and tie, and was shackled. There were no signs of blood on his shirt. The judge announced Routh will be sentenced on Dec. 18 at 9:30 a.m. He faces life in prison.
