The White House says President Barack Obama has told U.S. officials to maintain heightened airline security.

Obama made the comments during a briefing today with his national security team after a second incident was reported aboard a flight arriving in Detroit.

White House spokesman Bill Burton told reporters that Obama was told of the incident about 9 a.m. Hawaii time — about 90 minutes after the flight from Amsterdam landed. Burton says Obama also asked national security officials for another briefing as soon as possible.

Obama spent the earlier part of the morning playing basketball and working out during his vacation.
