King strongly criticized President Donald Trump's Executive Order 13769, which barred the admission of refugees to the U.S. and barred travel by nationals of several Muslim-majority countries to the country. King stated: "This is probably the worst foreign policy decision since the invasion of Iraq. What it's done is played right into ISIS's hands. They want us to turn this into a war of the west against Islam. They have explicitly said they want to drive a wedge ... There are 1.6 billion Muslims in the world and we don't want a war with all of them. We don't need a war with all of them. We're not opposed to all of them." King noted that U.S. forces fought alongside Muslim Iraqi troops, and that much valuable counterterrorism intelligence was shared with the U.S. by Muslim nations.
