At the Capitol, as administration officials presented their case for the nuclear deal with Iran, there was sharp criticism from Republican senators charging the deal is dangerous. Meanwhile, in New York, pro-Israel groups were among the 10,000 protesters who packed Times Square urging Congress to kill the deal, saying that concessions had been made to Iran that would threaten Israel. Congress has 60 days to decide whether to accept the agreement. President Obama has said he will veto any efforts to block it.
