Trump shooting suspect charged with gun crimes

A man suspected of plotting to assassinate former US president Donald Trump was charged with federal gun crimes on Monday.

Ryan Wesley Routh, 58, was charged with possession of a firearm as a convicted felon and possession of a firearm with an obliterated serial number at his initial court appearance.

Routh, who was arrested on Sunday after an alleged abortive bid to shoot the Republican presidential candidate at his West Palm Beach golf course, is expected to face further charges at a later date.

Routh appeared calm during the brief court hearing before Magistrate Judge Ryon McCabe of the Southern District of Florida, answering "yes" to several questions.

A detention hearing was scheduled for September 23 and an arraignment on further potential charges was set for September 30.

Routh was arrested on Sunday after a Secret Service agent on the former president's security detail saw what appeared to be the barrel of a rifle pointing out of a tree line on the perimeter of the Trump International Golf Course, according to a criminal complaint filed by an FBI special agent.

"The Agent fired his/her service weapon in the direction of the rifle," the complaint said.

Trump, who was slightly wounded in a July 13 assassination attempt during a campaign rally in Pennsylvania, was several hundred yards away when the golf course shooting occurred and was unharmed.

A man later identified as Routh was seen by a witness fleeing the area in a Nissan sport utility vehicle at high speed, the complaint said.

Routh was arrested by local police about 45 minutes later on I-95, a major north-south highway, and replied in the "affirmative" when asked if he knew why he was being stopped, it said.
