Shouting match: First it was sexting, then more sexting. Now Anthony Weiner is back on social media, this time confronting a heckler who called him a “scumbag.” In a viral video yesterday, it looked like Weiner was just going to walk away, until the guy said: “You’re married to an Arab.” Saul Kessler was referring to the politician’s wife, Huma Abedin, who works for Hillary Clinton. (Her ethnic background is diverse.) Weiner wasn’t going to take the slur, and got into a shouting match with Kessler inside the Brooklyn bakery. Weiner is Jewish, as were most of those inside the bakery.
