The president is no longer safe on the White House grounds, according to former Secret Service agent Dan Bongino, who once guarded presidents George W. Bush and Barack Obama.

Bongino made the stunning assessment in an interview Friday with Fox News. It followed an incident last Friday night when a man jumped the White House fence and may have roamed the property for as long as 15 minutes before he was stopped by the Secret Service.

Jonathan Tran, who carried two cans of mace, set off multiple alarms, Bongino said, and was even spotted by Secret Service officers, but was still able to come within “close proximity” of the White House and even reportedly “jiggled the door” to the executive mansion.

“The intruder set off multiple alarms, alarms that clearly showed someone breached the property, and he was seen by officers who didn’t think anything of it. This is a big story,” Bongino told Fox News.
