A man was reportedly detained Saturday night after he claimed he had a bomb in his truck at a White House checkpoint.
CNN reports that while it was not clear whether there was actually a bomb in the man's truck, White House security was upgraded.
The man arrived at the checkpoint at 11:05 p.m. Eastern time. Nearby streets were closed as a result. Four hours later, the checkpoint was blocked, but streets were reopened.
President Trump was in Florida at the time.

Earlier Saturday, another man was detained after jumping a bike rack near the White House. Last week, another man jumped the White House fence and was able to roam the grounds for 15 minutes before being caught.
The Secret Service said the investigation was "ongoing."
