Fighter jets intercepted a small plane that strayed into President Obama's airspace over Los Angeles today, and police found 40 pounds of marijuana after it landed, officials say.

Obama was headed to LAX aboard his Marine One helicopter about 11 a.m. PT when the single-engine Cessna 182 entered the temporarily restricted zone, the North American Aerospace Defense Command said in a statement. Two F-16s scrambled from March Air Reserve Base in Riverside County and followed the plane until it landed in Long Beach about 11:30 a.m. PT. (There's some confusion in news reports about the time, which Colorado-based NORAD reported in Mountain Standard Time, an hour ahead of Pacific Time.)

Long Beach police found the marijuana during a search, a law enforcement source told the Associated Press. The pilot has not been identified.

Obama was returning to LAX from a fundraiser, bound for Air Force One and another money-raising stop in San Francisco. The Federal Aviation Administration had notified pilots of an 8-mile no-fly zone.

The Secret Service said the president was never in danger.
