Senate Majority Leader Mitch McConnell (R-Ky.) on Sunday said the courts will decide if President Donald Trump’s ban on nationals from seven Muslim-majority countries entering the United States is too broad.

“Well, if they’re looking to tighten the vetting process, I mean who would be against that?” McConnell asked on ABC’s “This Week.”

“But I am opposed to a religious test. The courts are going to determine whether this is too broad.”

{mosads}Trump on Friday signed an executive order that called for a 90-day ban on nationals from seven predominantly Muslim countries entering the United States.

McConnell said some of “the best sources in the war against radical Islamic terrorism are Muslim.”

“It’s hopefully going to be decided in the courts as to whether or not this has gone too far,” McConnell said. “I don’t want to criticize them for improving vetting. I think we need to be careful. We don’t have religious tests in this country.”
