The armed man accused of scouting President Trump’s Southern California golf club before the commander in chief’s visit was a decorated former US Marine who completed combat deployments to both Iraq and Afghanistan.

Jeanine John Taele, 38, of Downey, served in the Marine Corps from March 2008 until March 2016, reaching the rank of corporal while assigned as a warehouse clerk with the elite 1st Reconnaissance Battalion at Camp Pendleton, according to military records obtained by the California Post.

Taele deployed to Iraq from October 2008 through March 2009, and later served in Afghanistan from June through December 2010, records show.

His military file shows he earned two Marine Corps Good Conduct Medals, awarded for repeated periods of honorable and disciplined service, along with a Navy Unit Commendation recognizing exceptional performance by his unit.

He also received the National Defense Service Medal for serving during the post-Sept. 11 Global War on Terror era, the Global War on Terrorism Service Medal, the Iraq Campaign Medal and Afghanistan Campaign Medal for his overseas deployments, two Sea Service Deployment Ribbons recognizing extended overseas assignments, and the NATO International Security Assistance Force Medal for supporting the alliance’s mission in Afghanistan.

Federal investigators are digging into Taele’s history, including whether he had any ties to extremist groups or connections to the Californian men at the center of a foiled terror plot at the UFC event at The White House, a law enforcement source told The Post.

Taele now faces federal charges after authorities say they found him armed at Trump National Golf Club Los Angeles in Rancho Palos Verdes just days before the president’s Aug. 4 fundraising visit at the location.

He was charged in a federal criminal complaint with possessing an unregistered short-barreled rifle, a felony carrying a maximum sentence of 10 years in prison.

Agents conducting advance security planning spotted Taele on July 31 walking around the golf course and wearing an earpiece while photographing and filming security preparations, according to federal prosecutors.

He allegedly returned to the club on Aug. 2, where he falsely claimed he worked for the State Department on a security detail and admitted he had a loaded firearm in his pickup truck.

Deputies responding to the scene also discovered Taele was wanted in an unrelated robbery case out of El Segundo. Authorities recovered a loaded 9mm pistol, hollow-point ammunition, binoculars and a badge labeled “security protection agent” from his truck, prosecutors said.

A subsequent search of his home uncovered what investigators described as an illegally modified AR-platform rifle, additional firearms, body armor, high-capacity magazines, communications equipment and notebooks containing 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 US Attorney Bill Essayli said in announcing the federal charges. “Federal and local law enforcement stepped in early and prevented what could have been a dangerous situation from occurring. This investigation remains ongoing.”

FBI Los Angeles Assistant Director in Charge Patrick Grandy said Taele’s conduct “raised serious red flags.”

“There is no room for error, particularly in light of previous attempts on President Trump’s life, and the FBI’s Joint Terrorism Task Force, working with our partners at the U.S. Secret Service, the ATF, and the Los Angeles County Sheriff’s Department, will investigate this case thoroughly,” Grandy said.

President Trump later downplayed the incident during an interview with Fox News.

“The only thing I get a little solace from is they say only consequential presidents, and I am definitely consequential,” Trump said. “I have no choice,” he added while pivoting to discuss Iran. “They can’t have a nuclear weapon.”

Taele also faces state firearms charges in Los Angeles Superior Court in addition to the pending federal case.
