Republican presidential nominee Donald Trump received his second intelligence briefing on Friday at the FBI’s field office in New York City.

Trump received his first intelligence briefing in the same location last month, but also brought along New Jersey Gov. Chris Christie and retired Lt. Gen. Michael Flynn, a former Defense Intelligence Agency director. It’s uncertain, however, whether the same advisors attended Friday’s scheduled meeting.

Receiving such briefings has been a longstanding tradition for presidential candidates. Director of National Intelligence James Clapper recently denied House Speaker Paul Ryan’s request to prohibit Democratic nominee Hillary Clinton from receiving the national security briefings for “for the duration of her candidacy for president” due to her controversial handling of a private email server during her tenure as secretary of state.

“Nominees for president and vice president receive these classified briefings by virtue of their status as candidates, and do not require separate security clearances before the briefings,” Clapper replied.

The former secretary of state spent two hours with U.S. intelligence officials last Saturday in White Plains, New York, during her first briefing.
