NEWARK, New Jersey (AP) — A security guard at Newark Liberty International Airport charged with threatening President Barack Obama is due in court.

John Brek is expected to hear a judge in Newark review the charges via a video link on Thursday.

Brek was arrested Tuesday night, several hours after a Continental Airlines employee reported overhearing him make threatening comments at an airport coffee cart. Obama arrived at the airport Wednesday afternoon to campaign for New Jersey Gov. Jon Corzine.

The 55-year-old is charged with making terroristic threats against the president and is held on $100,000 bail.

Brek works for a private security company that has a contract at the airport. Its employees' screen the credentials of other airport workers.
