Routh, who is being held without bail, was originally charged with possession of a firearm as a convicted felon and possession of a firearm without a serial number after the Secret Service said agents encountered him at Trump International Golf Club on Sept. 15.

Last week, Routh was indicted on three new charges, including the attempted assassination of a major presidential candidate, possessing a firearm in furtherance of a crime of violence and assaulting a federal officer.

Prosecutors claim Routh was in West Palm Beach on Sept. 15 to assassinate Trump. They say he created a list of venues and dates from August to October where Trump was scheduled to appear while campaigning for a second term as president. They also said Routh sent a letter to a witness, saying “This was an assassination attempt on Donald Trump but I failed you.”

A Secret Service agent discovered the barrel of an SKS-style rifle protruding through the tree line near the golf course’s sixth green. The agent shot at Routh, who fled the scene but was arrested on a nearby highway. The former president was not injured and was rushed off the golf course to safety.

According to the complaint, agents found the loaded SKS-style rifle, two backpacks and a digital camera. The government argues Routh was in West Palm Beach “for one reason and one reason only and that was to kill the former President of the United States.”

It was the second assassination attempt on Trump after he was clipped in the ear by a bullet while speaking at an outdoor rally on July 13, in Butler, Pa. One supporter was killed in the shooting and several others were injured. The alleged gunman, who was perched on a nearby roof, was killed by Secret Service.

Last week, the U.S. Senate passed a House bill to provide equal Secret Service protection to presidents and all major party candidates following both assassination attempts on Trump. The Enhanced Presidential Security Act is awaiting President Joe Biden‘s signature.
