The FBI says it recovered the stark black flag of the Islamic State extremist group from the truck that an American man from Texas smashed into New Year’s partygoers in New Orleans’ French Quarter. Wednesday's attack killed 15 people. The investigation is expected to look at any support or inspiration that Shamsud-Din Jabbar may have drawn from that violent Middle East-based group or any of at least 19 offshoots around the world. President Joe Biden says the FBI told him that “mere hours before the attack, (Jabbar) posted videos on social media indicating that he was inspired” by the Islamic State group.
