PORTLAND, Ore. (AP) — There's no dispute that a 19-year-old Muslim college student tried to set off a car bomb at Portland's 2010 Christmas tree lighting ceremony, but how he reached that point is the crux of a trial that began in federal court this week.

A jury of seven men and nine women will decide whether this was a case of the U.S. government preventing the radicalization of a young Somali-American man, or was instead the FBI's coercion of an impressionable, hotheaded braggart into a plan he was otherwise incapable of carrying out.

Mohamed Mohamud's attorneys began to build their case during opening statements Friday, arguing that he was the victim of a sophisticated manipulation by undercover FBI agents.
