A major security investigation unfolded in Southern California after authorities detained an armed man near one of President Donald Trump’s properties just before the president’s arrival.
Federal and local law enforcement agencies are now working together to determine whether the incident was an isolated weapons case or something more serious.
The arrest triggered an immediate response from multiple agencies responsible for protecting the president, prompting investigators to examine the suspect’s movements, statements and the items recovered during the investigation.
Although officials say there is no confirmed plot at this time, they continue to describe the case as active.
An armed man was arrested outside Trump National Golf Club in Rancho Palos Verdes, California, after federal agents reported suspicious activity on the property before President Donald Trump’s scheduled visit, according to the Los Angeles County Sheriff’s Department.
The arrest occurred Sunday, two days before Trump arrived in Southern California for a Republican National Committee dinner at the golf club after traveling aboard Air Force One.
According to a federal law enforcement source familiar with the investigation, the U.S. Secret Service is examining whether the suspect posed a threat to the president.
The source told CNN there is currently no indication that the suspect was actively planning an attack on Trump but emphasized that investigators are continuing to evaluate the evidence.
Authorities identified the suspect as 38-year-old Jeanine John Taele of Downey, California.
The Los Angeles County Sheriff’s Department said Taele was already under investigation by the El Segundo Police Department in connection with a separate robbery case before his arrest at the golf club.
Investigators said federal agents first noticed Taele during a security assessment conducted Friday before the president’s visit.
According to the U.S. Department of Justice, agents observed Taele walking around the golf course while wearing an earpiece and taking photographs and videos of federal agents and their security operations.
Officials said Taele left the property but returned Sunday, when he approached federal agents and allegedly claimed he worked for the U.S. State Department and was part of a security detail.
Authorities said Taele also informed officers that he had a loaded firearm inside his vehicle.
After searching the vehicle, deputies arrested him on state charges that included carrying a concealed firearm and possessing prohibited ammunition.
On Tuesday, Taele pleaded not guilty to four state charges, including second-degree robbery related to an alleged November 2025 incident and three weapons offenses connected to his August 2 arrest.
Court records show a judge set his bail at $250,000, ordered him not to possess firearms, directed him to stay away from Trump National Golf Club and required him to remain in California while the case proceeds.
Federal prosecutors also filed a criminal complaint charging Taele with possessing an unregistered short-barreled rifle, a felony offense punishable by up to 10 years in federal prison if convicted.
He is expected to make his initial appearance Wednesday in federal court in Los Angeles.
As part of the investigation, members of the FBI’s Joint Terrorism Task Force executed a search warrant at Taele’s residence on Monday.
According to the sheriff’s department, investigators recovered what they described as an illegally modified AR-style rifle, a .45-caliber pistol, body armor, high-capacity magazines, ammunition, radio signal devices and several notebooks containing what officials called “concerning statements.”
“While we are still investigating the motives of this individual, we are thankful he was apprehended before the President’s visit,” First Assistant U.S. Attorney Bill Essayli said in a statement.
Essayli added that federal and local law enforcement “stepped in early and prevented what could have been a dangerous situation from occurring,” CNN reported.
The FBI, Secret Service and local law enforcement agencies continue to investigate the incident, and officials have indicated that additional charges could be filed as more evidence is reviewed.
