A federal judge in Florida on Monday ordered that Ryan Routh, the alleged would-be assassin of Donald Trump, be held without bail pending trial.

The order came hours after prosecutors in a court filing said that Routh stalked Trump for a month in Florida before his arrest on Sept. 15. Routh, 58, was apprehended less than an hour after a Secret Service agent fired at Routh, who was allegedly laying in wait with a rifle outside a golf course where the former president was playing.

Prosecutors said during a hearing in U.S. District Court in West Palm Beach, Florida, on Monday that they plan to ask a grand jury to indict Routh on criminal charges related to an attempted assassination of Trump. But for now, he only faces two weapons-related charges.

The court filing disclosed that Routh months earlier had given another person a box containing a handwritten letter that said, "This was an assassination attempt on Donald Trump but I failed you."

A prosecutor during the hearing Monday told Magistrate Judge Ryon McCabe that the only "established ties" that Routh had to the federal Southern District of Florida "is for one reason only and that was to kill former President Trump."

Routh's cellphone data shows that he "traveled from the Greensboro, North Carolina, area, to West Palm Beach, Florida," on Aug. 14, according to the filing in U.S. District Court in West Palm Beach.

"On multiple days and times from August 18, 2024, to September 15, 2024, Routh's cell phone accessed cell towers located near Trump International [Golf Course] and the former President's residence at Mar-a-Lago" in Palm Beach, the filing said.

And when he was arrested after fleeing his hiding spot just outside the golf course, Routh had in his possession a "handwritten list of dates in August, September, and October 2024 and venues where the former President had appeared or was expected to be present" the filing said.

The filing, known as a proffer, was made by prosecutors in support of their request that a judge order the Routh held without bail at the hearing.

Routh is charged with possession of a firearm by a convicted felon and possession of a firearm with an obliterated serial number.

Trump, who is the Republican nominee for president, narrowly survived an assassination attempt during a campaign rally in western Pennsylvania on July 13. One rally attendee was killed and two other attendees were wounded in that shooting, which ended when a Secret Service sniper killed the gunman.

On Monday, after a nearly three-hour detention hearing for Routh, Trump accused the Department of Justice of "mishandling and downplaying the second assassination attempt on my life since July."

"The charges brought against the maniac assassin are a slap on the wrist," Trump said in a statement. "It's no wonder, since the DOJ and FBI have been coming after me nonstop with Weaponized Lawfare since I announced my first Historic Campaign for the Presidency."

Trump also suggested that the state of Florida handle the criminal prosecution of Routh "if the DOJ and FBI cannot do their job honestly and without bias."

On Sept. 15, Trump was playing on the fifth hole at Trump International when a Secret Service agent conducting a security sweep "spotted the partially obscured face of a man in the brush along the fence line" near the sixth hole's green, the court filing said. The man was later identified as Routh.

The agent after seeing the barrel of a rifle aimed directly at him jumped off his golf cart, drew his weapon, and then fired at Routh, according to the filing.

Routh then fled the area.

Trump, who was several hundred yards away at the time, was "immediately removed" from the course by Secret Service agents, the filing said.

Routh was apprehended by police about 45 minutes later after fleeing in a Nissan Xterra.

FBI agents who searched the area outside the golf course where he had first been spotted found an SKS semiautomatic rifle that had a scope attached and an extended magazine, according to the filing, which said there were 11 rounds found in the rifle, including "a round in the chamber." The rifle's serial number was obliterated.

"The agents also found a digital camera, a backpack and a reusable shopping bag hanging from the chain link fence," the filing said.

Both the backpack and the shopping bag "contained plates" which later ballistics testing showed "were capable of stopping small arms fire," the filing said.

The Nissan that Routh was driving had a different license plate than the one registered to the vehicle, prosecutors said in the filing.

"During a search of the Nissan Xterra ... FBI agents found two additional license plates," the filing said.

"The agents also found six cellphones. One of the cell phones contained a Google search of how to travel from Palm Beach County to Mexico," the filing said. "The agents also found 12 pairs of gloves; a Hawaii Driver's License in the Defendant's name; a passport in the Defendant's name."

And the agents found the handwritten list of dates where Trump had appeared or was expected to be present, according to the filing.

Also in the car was "a notebook with dozens of pages filled with names and phone numbers pertaining to Ukraine, discussions about how to join combat on behalf of Ukraine, and notes criticizing the governments of China and Russia," the filing said.

FBI agents also reviewed a book apparently written by Routh in February 2023, tilted, "Ukraine's Unwinnable War: The Fatal Flaw of Democracy, World Abandonment and the Global Citizen-Taiwan, Afghanistan, North Korea, WWIII and the End of Humanity."

Three days after his arrest, a civilian witness contacted authorities and told them that "Routh had dropped off a box at his residence several months prior," according to the filing.

"The witness stated the box contained ammunition, a metal pipe, miscellaneous building materials, tools, four phones, and various letters," the filing said.

"One handwritten letter, addressed to 'The World,' stated, among other things, 'This was an assassination attempt on Donald Trump but I failed you. I tried my best and gave it all the gumption I could muster.'"

Among other things, the letter said, "He [the former President] ended relations with Iran like a child and now the Middle East has unraveled."

Routh was legally barred from possessing a firearm because of two prior felony convictions in North Carolina state court, which are detailed in Monday's court filing.

He was convicted in December 2002 of possessing a weapon of mass destruction, described as a binary explosive device.

In March 2010, he was convicted of multiple counts of possession of stolen goods, the filing noted.
