President Donald Trump lashed out at Republican Sens. John McCain and Lindsey Graham on Sunday after the two issued a joint statement warning that his executive order banning immigrants from seven predominantly Muslim countries as “will become a self-inflicted wound in the fight against terrorism.”

“Our most important allies in the fight against ISIL are the vast majority of Muslims who reject its apocalyptic ideology of hatred,” the senators’ statement said. “This executive order sends a signal, intended or not, that America does not want Muslims coming into our country. That is why we fear this executive order may do more to help terrorist recruitment than improve our security.”
