UPDATE:
Reports are now claiming it was a parody ISIS Flag:
The “ISIS” flag on the CNN #FakeBombs is actually a picture of some naked chicks and the slogan “Get Er Done”. Not ISIS. Can’t find any Google reverse image search hits except some reference to “Boars Butt Brewery” in Charletown, SC. BOTTOM LINE: Looks like a LibTard. pic.twitter.com/IwakjKvFQy
