evidence: On Sunday, Trump tweeted he would designate Antifa a terrorist organization, despite the US government having no existing legal authority to do so. Antifa, short for anti-fascists, describes a broad, loosely-organized group of people whose political beliefs lean toward the left — often the far-left — but do not conform with the Democratic Party platform. [...] The fake account, @ANTIFA_US, tweeted Sunday, "ALERT Tonight’s the night, Comrades Tonight we say "F**k The City" and we move into the residential areas… the white hoods…. and we take what’s ours #BlacklivesMaters #F**kAmerica." "Absolutely insane," Trump Jr. wrote on Instagram, sharing a screenshot of the tweet, "Just remember what ANTIFA really is. A Terrorist Organization! They’re not even pretending anymore."
