Bernie Sanders may be ethnically Jewish, but his campaign is rapidly turning out to be the most anti-Semitic in decades.

The latest scandal to rock the Vermont senator’s campaign is his overnight reversal on endorsing Cenk Uygur, the Armenian genocide-denying founder of liberal news network The Young Turks. Sanders retracted his endorsement of Uygur for California’s 35th congressional seat since vacated by Katie Hill, after rare bipartisan backlash.
