Mike Huckabee: Nuclear deal marches Israel to oven

Republican US presidential candidate Mike Huckabee has criticised the Iran nuclear deal as “marching the Israelis to the door of the oven”, a reference to the Holocaust.

The former Arkansas governor tweeted the remark a day after first making the comparison when denouncing US President Barack Obama for his role in the agreement.

Democratic National Committee chairwoman Debbie Wasserman Schultz said Huckabee’s statement was “grossly irresponsible” and called on him to apologise.
