Trump says he's naming antifa a 'Terrorist Organization.' Can he do that?

President Donald Trump tweeted on Sunday that the U.S. government would be "designating ANTIFA as a Terrorist Organization."

There were just two problems with that. First, he doesn't appear to have the legal authority to do so. And second, it's by no means clear the loosely defined group of radical activists is an organization at all.

The Trump administration's push to crack down on antifa - short for "anti-fascist" - comes as large and small businesses in a host of American cities were looted and vandalized as people protested the death of a black man, George Floyd, at the hands of a white police officer in Minneapolis.
