The FBI has also informed me that he uploaded videos to social media just hours before the attack, indicating that he was inspired by IS, says Biden.
People were killed and many injured when the suspect, a 42-year-old army veteran from Texas, mowed them down with a pickup truck on Bourbon Street on New Year's Eve.
The American President says that the FBI has told him that they are investigating possible connections to the exploded Tesla outside Donald Trump's hotel in Las Vegas, but that there is nothing more to say about it for the time being.
Biden highlighted New Orleans and the French Quarter where the attack took place as a unique, world-renowned location that exudes charm and joy.
I know that there are so many around the world who love New Orleans for its history, culture, and above all, the people who live here, says Biden, and says he is convinced that no one, not even a horrific attack, can kill the city's soul and spirit.
Several world leaders, including Sweden's Prime Minister Ulf Kristersson, have condemned the attack.
"My thoughts go to the victims and their families. Sweden stands behind the USA during these tragic times", writes Kristersson in a post on X.
