Donald Trump has criticised US authorities and law enforcement agencies in the wake of the deadly New Orleans attack, saying they are "ineffective" and there is "virtually non-existent leadership", writes BBC.

While the president-elect did not directly address Wednesday’s attack, he took to Truth Social a few hours ago to allege that authorities - like the FBI and the Department of Justice – "have not done their job" in protecting Americans.

He adds: "The CIA must get involved, NOW, before it is too late".

"The USA is breaking down - A violent erosion of safety, national security, and democracy is taking place all across our nation. Only strength and powerful leadership will stop it. See you on January 20th. MAKE AMERICA GREAT AGAIN!", - he writes.
