Huddled masses, take a number. On Thursday, the U.S. House passed a bill — which Obama has vowed to veto should it clear the Senate after Thanksgiving — adding tough migrant screening requirements. It’s drawn comparisons to America’s World War II-era refusal to accept European Jewish refugees, who were subsequently murdered en masse. But 26 U.S. governors say security concerns dictate they shun Syrian newcomers to their states, even if they have no power over the asylum process. They could, it’s feared, slow resettlement while sowing anti-immigrant sentiment among their constituents.
