Twitter placed a warning on a tweet from a Florida congressman about hunting antifa.

No sooner had President Trump announced he would label antifa – a left-wing, anti-fascist political movement – a terrorist organization, than Republican Rep. Matt Gaetz apparently decided it was open season.

Twitter, which recently put a “glorifying violence” warning label on one of Trump’s tweets, promptly slapped a warning on Gaetz’s tweet.

“Antifa is a terrorist organization, encouraging riots that hurt Americans,” tweeted Gaetz, an avid Trump supporter.

On Monday, a Twitter account advocating violence related to the protests and ostensibly aligned with antifa turned out to be fake, reported NBC News.
