New Orleans attacker had 'remote detonator' for explosives in French Quarter, Biden says

Biden stated that federal agents are investigating potential links to the Las Vegas explosion, also probed as a terror attack, and urged them to "accelerate" their efforts. Fourteen people were killed, and Jabbar died in a shootout with police. 

"As of now, they've just been briefed," Biden said. "They have not found any evidence of such a connection thus far. I've directed them to keep looking." 

Authorities had been investigating a potential military connection between Jabbar and the Las Vegas suspect, who law enforcement identified to The Associated Press as Matthew Livelsberger.

Jabbar, a U.S. native born in Texas, had previously served in the U.S. military. Authorities are still investigating how and when he became radicalized.
