Congressional lawmakers demanded answers Wednesday about the FBI's response to the Jan. 1 truck attack in New Orleans that killed 14 people, questioning why the bureau's top official in the city was out of town and raising concerns about its initial, erroneous assertion that the rampage was “not a terrorist event.” In a series of letters, Sen. Chuck Grassley, chairman of the Senate Judiciary Committee, and Sen. Ron Johnson, chairman of the Senate's Permanent Subcommittee on Investigations, also suggested Facebook missed red flags and asked the social media company to provide a timeline of when it became aware of threatening videos Shamsud-Din Jabbar posted before he plowed a pickup truck through a crowd of New Year's revelers.
