Trump was not at the resort at the time, although he was scheduled to arrive there later Friday. The president had been briefed, said press secretary Stephanie Grisham. There were no changes to his travel plans.

The black SUV breached security a little after 11:30 a.m. at the main entrance of the resort, according to the Palm Beach County Sheriff’s Office. Officers fired shots and the SUV raced off. It was pursued by the Highway Patrol and a sheriff’s office helicopter.

Investigators say the vehicle approached the checkpoint at a high rate of speed and did not appear to brake in any way, according to a law enforcement official who spoke on condition of anonymity in order to discuss the investigation.

The official stressed the investigation was just beginning and the information was preliminary. The breached checkpoint, one of several set up when Trump is traveling to the resort, is a few blocks away from the actual resort. The Secret Service said it would have a news conference later Friday.

Several hours after the breach, cars were allowed to drive on streets near the resort. Armed guards were present as usual but did not appear to be on a higher alert than normal.

Mar-a-Lago has been the scene of several intrusions since Trump became president. On Jan. 5, just hours after Trump and his family had left the club following a two-week vacation, a Florida man who had been dishonorably discharged from the Marines for sex offenses was arrested after he got past two checkpoints by falsely identifying himself as part of the president’s helicopter crew.
