National Guard DC shooting: Suspect update

The investigation continues after one National Guardsmen was fatally shot and another critically wounded in an apparent targeted shooting in Washington, D.C. the day before Thanksgiving. U.S. authorities now say they believe the Afghan immigrant accused in the ambush attack was not radicalized until after he came to the United States, Homeland Security Secretary Kristi Noem said on Sunday. Retired FBI Special Agent Scott Duffey joined LiveNOW from FOX's Carel Lajara to discuss the latest developments in the case.
