In November of 2010, a young Somali American man named Mohamed Mohamud was arrested in Portland, Oregon. He was charged with attempting to use a weapon of mass destruction after allegedly trying to set off what he believed to be a bomb at a popular tree-lighting ceremony in Pioneer Square.
However, the bomb was a fake, given to him by undercover FBI agents. Now a federal trial is underway to determine his guilt.
We speak to April Baer of Oregon Public Broadcasting, who has been covering this story.
