At the White House on March 18, the Secret Service detained a man who claimed to have a bomb in his vehicle.
The Secret Service said they detained the man at 11:05 p.m. at a White House security checkpoint, CNN reports. They did not confirm if a bomb was in the vehicle. Security at the White House was immediately upgraded.
CNN correspondent Ryan Nobles tweeted live from the scene, providing a photo of a robot checking the vehicle.
"A robot inspects the trunk of the suspect's car. Still parked outside the White House," he wrote with the image.
"We just saw a bomb squad member dressed in full gear (like the Hurt Locker) pulling things out of the trunk and inspecting them," a follow-up tweet read.
"It appears that the car is still running and in the same spot it was when the incident began almost three hours ago," Nobles wrote.
The security checkpoint remained blocked four hours after the incident, but streets had reopened, according to CNN. Bomb technicians and other additional security personnel had left the area by this time.
The Secret Service is referring to the incident as an "ongoing criminal investigation."
President Donald Trump was not at the White House when the incident occurred; he is in Florida at his Mar-a-Lago estate.
Also on March 18, police arrested a man after he jumped over a bicycle rack in front of the White House. He said he had a document he wanted to deliver to the White House. A weapon was not found on his person, a law enforcement official said, and he did not make it over the White House fence.
There was also a breach in security on March 10 at the White House. At 11:21 p.m. an individual climbed over a 5-foot high fence, then an 8-foot vehicle gate and finally a 3.5-foot fence near the southeast corner of the East Wing of the White House grounds, according to a March 17 Secret Service press release. More than 15 minutes later at 11:38 p.m., the individual was taken into custody without incident.
The Secret Service confirmed that the individual did not gain entry into the White House.
"The men and women of the Secret Service are extremely disappointed and angry in how the events of March 10th transpired," the release said. "Immediate steps have been taken to mitigate lapses in security protocols even as the investigation continues. These steps include additional posts, technology enhancements, and response protocols."
