A U.S. Air Force fighter jet intercepted a small plane flying near President Trump’s golf club in New Jersey, where the president is spending the weekend.

The White House confirmed Sunday that a “small, low wing general aviation aircraft” entered a “no fly” zone near Trump’s golf club in Bedminster one day earlier. An F-16 met the plane and escorted it out of the restricted area, White House spokeswoman Lindsay Walters said in a statement.

“The aircraft was met upon landing at Sky Manor airport in Pittstown, NJ and the pilot interviewed by law enforcement and deemed a non-threat,” Walters said.

The Associated Press first reported that the plane was spotted flying Saturday around 12:30 p.m. “without proper clearances or communications.”

Trump is spending the weekend at his New Jersey golf club for the second time in three weeks. Last weekend, he stayed at his Turnberry golf resort in Scotland during his weeklong trip to Europe.

The president did not have any public events scheduled this weekend in New Jersey.

He is slated to return to the White House on Sunday evening.
