Danny Danon, the Israeli ambassador to the United Nations, tore into Rep. Ilhan Omar after an advocacy group named her “Antisemite of the Year.”

“@StopAntisemites just named Congresswoman Ilhan Omar it’s 2019 Antisemite of the Year,” Danon said Monday on Twitter. “Here is a clear opportunity to prove that all the talk about standing up to #antisemitism is not just an empty promise, but will be followed by action.”
