A Washington state man accused of making an email threat against President Barack Obama and brandishing a shotgun at officers who came to his door is scheduled to appear in federal court.

Secret Service spokesman Brian Leary says 31-year-old Anton Caluori was arrested Tuesday at an apartment in Federal Way for investigation of making threats against the president and assault on a federal officer.

U.S. attorney's spokeswoman Emily Langlie says the threat was sent to a general purpose FBI email address.

A Secret Service agent and a Federal Way police officer went to an apartment, knocked and announced themselves for about three minutes, then found themselves facing a man armed with a shotgun when the door opened.

Leary says Caluori is set to appear at 2 p.m. Wednesday in court.
