Shamsud-Din Jabbar, the attacker in the New Orleans incident, stored suspected bomb-making materials at his home and planned his attack over six weeks.
Federal authorities discovered a workbench and hazardous materials linked to bomb-making at Jabbar's Houston residence during a search.
The attack, which resulted in 14 fatalities and approximately 30 injuries, involved Jabbar, a former Army soldier, who demonstrated his intentions via social media.
Authorities ultimately killed Jabbar in a firefight, and crude bombs were found in the vicinity, indicating his intent to cause further harm.
President Joe Biden plans to visit New Orleans to console the affected families, as the city enhances security measures ahead of Carnival season and the Super Bowl.
