The first law enforcement officer in the U.S. ever to be charged with a terrorism offense is set to go to trial later this month.
Jury selection began Tuesday in federal court in Alexandria, Virginia, in the case against Nicholas Young, who was a police officer in the region's Metro system when he was arrested last year in a government sting.
Prosecutors say Young bought nearly $250 in gift cards he intended for the Islamic State group, giving the cards to an individual who turned out to be an FBI source.
Judge Leonie Brinkema ordered a one-week delay after defense lawyers asked for more time to review a new batch of evidence.
Young's lawyers say the sting operation amounts to entrapment.
Documents show Young had been under surveillance since 2010.
The trial is expected to include evidence that Young trafficked in Nazi memorabilia, evidence that Young's lawyers wanted tossed out as overly inflammatory.
