Sen. Lindsey Graham Lindsey Olin GrahamSenate Republicans signal openness to working with Biden Loeffler calls for hearing in wake of Netflix's 'Cuties' Quinnipiac poll shows Graham, Harrison tied in South Carolina Senate race MORE (R-S.C.) is predicting that President Trump would win if the challenge to his temporary ban on travelers from seven Muslim-majority nations reaches the Supreme Court.

“I think he’ll probably prevail at the Supreme Court,” he said Wednesday on “The Mike Gallagher Show." "Here’s what most people don’t get.

“The proposal is to slow down travel for 90 days, not to revoke everybody’s visa,” the 2016 GOP presidential candidate added. "I think he’ll win on that, because that makes sense to me.”

“I support a timeout in terms of bringing people into the country from the seven countries in question with the understanding that 60,000 to 100,000 people already have visas from those countries that work in America, go to school in America [and] live in America.”

But Graham stressed that all immigrants from the targeted countries can't be lumped "in the same boat."

“So a translator, an interpreter, who served with our forces in Iraq should not be subject to this ban because they’ve proven themselves worthy of coming into our country on the battle,” Graham said.

“But I don’t mind saying you can’t travel on that visa for 90 days until we get a better grip on who’s coming in the future to change our vetting process for future flow.”

Trump said Wednesday that America’s “security is at risk” while a panel of federal judges weighs whether a court order blocking his travel ban should be lifted.

One day earlier, the president said the legal battle over his “common-sense” measure may ultimately reach the Supreme Court.

Trump issued an executive order last month imposing a 90-day ban on visitors from Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen.

The directive also froze general refugee admissions into the U.S. for 120 days and indefinitely paused Syrian refugees due to Syria’s ongoing civil war.

Critics argue Trump’s order is unconstitutional and biased against Muslims, while the president contends it will prevent radical Islamic terrorism in the U.S.
