Marco Rubio: We Can't Take In Syrian Refugees After Paris Attacks

After saying earlier that he would be open to the idea of allowing Syrian refugees into the U.S., Sen. Marco Rubio (R-Fla.) said Sunday that "we won't be able to take more refugees" in the wake of the Paris terror attacks.

"It’s not that we don’t want to," Rubio said on ABC's "This Week with George Stephanopoulos." "It’s that we can’t."

Back in September, the GOP presidential hopeful said that under a Rubio administration, "We would be potentially open to the relocation of some of these individuals at some point in time to the United States." But he also added at the time that he'd "always be concerned" that "someone with a terrorist background could also sneak in" among the refugees.

A series of coordinated attacks in Paris on Friday claimed at least 129 lives and wounded at least 350. French President Francois Hollande has attributed the attacks to the Islamic State. At least one of the attackers held a Syrian passport and appears to have come through Greece among the throngs of refugees, increasing fears that members of ISIS may use the crisis as a method of entry.

In the wake of the attacks, several Republicans seeking the GOP presidential nomination have called for a tighter U.S. policy on refugees. The White House has made plans to accept 10,000 Syrian refugees in the next year, a small number compared to U.S.'s European allies.

Sen. Ted Cruz (R-Texas) said Saturday allowing thousands of "Syrian Muslim refugees" into the country is "nothing less than lunacy," while also saying that Christians fleeing persecution deserve "safe haven." GOP frontrunner Donald Trump, meanwhile, has said allowing thousands of refugees with "big problems" into the country is "just insane."
