The US Secret Service detained a man who drove up to a White House checkpoint late Saturday night and claimed to have a bomb in his vehicle, two law enforcement officials told.

There was no confirmation on whether there was any device in the vehicle, but security at the White House was immediately upgraded. The vehicle is being checked, the officials said.
The incident occurred at 11:05 p.m., the Secret Service said. President Donald Trump is not at the White House. He is at his Mar-a-Lago estate in Florida

Several streets around the White House remained closed early Sunday in what the Secret Service described as an “on-going criminal investigation.”
Earlier Saturday, another person was arrested after jumping over a bicycle rack in front of the White House. The man, who never made it to the White House fence, was carrying a document he wanted to deliver to the White House and did not have a weapon, a law enforcement official said.

he incidents come a week after a man breached the White House grounds — and was on the grounds for more than 15 minutes.
