NYPD's John Miller on "critical stage" in N.J. and N.Y. bombings investigation
The FBI became aware of New Jersey and New York bombings suspect Ahmad Rahami in 2014 after a neighbor heard his father call him a terrorist, but federal agents found no ties to terrorism and closed their investigation. John Miller, NYPD deputy commissioner of intelligence and counter-terrorism and former CBS News senior correspondent, joins "CBS This Morning" to discuss the ongoing investigation into Rahami.
