Both Donald Trump and Ted Cruz will speak at a Washington, D.C. rally against the Iran nuclear deal.

The two Republican presidential candidates each will appear at a Sept. 9 rally sponsored by the Zionist Organization of America, the pro-Israel group announced Thursday.

The deal, which lifts sanctions on Iran in exchange for it curbing its nuclear program, was finalized between Iran and six world powers, including the United States, last month. Congress will vote on it in September, and President Obama has promised to veto any rejection of the deal.

The Israeli government and numerous American Jewish organizations, including the American Israel Public Affairs Committee (AIPAC) oppose the deal. However, hundreds of rabbis and several prominent Jews, including some Democratic congressmen, have come out in support of it.

Cruz has long been a staunch supporter of Israel. He spoke in the Senate about the three Israeli teens kidnapped and murdered by Hamas last year, and was booed during a speech in which he said those that hate Israel, hate America:

“Those who hate Israel hate America,” he added, undeterred. “Those who hate Jews hate Christians. If those in this room will not recognize that, then my heart weeps. If you hate the Jewish people you are not reflecting the teachings of Christ. And the very same people who persecute and murder Christians right now, who crucify Christians, who behead children, are the very same people who target Jews for their faith, for the same reason.”
