Several streets around the White House were closed in what remained an ongoing situation, CNN reported. A robot was said to be inspecting the trunk of the suspect's vehicle, which was still parked outside the White House.

He was spending the weekend at his Florida resort, Mar-a-Lago, where he arrived Friday evening, his fifth visit since he took office Jan. 20. He is in Palm Beach with his wife Melania and son Barron, according to reports.

On March 10,  a man jumped a fence, carrying a letter for Trump but was arrested near the south entrance, CNN reported.
