WASHINGTON — The Senate will consider rigorous new screening procedures for Syrian and Iraqi refugees seeking to enter the United States as national security looms large in an election year.

Propelled by the Islamic State group’s attacks in Paris, the GOP-backed legislation raced through the House in November with 289 votes. That veto-proof margin included 47 Democrats despite the Obama administration’s opposition to the measure.

The legislation will have a much harder time making it through the Senate in the week ahead.

Majority Leader Mitch McConnell, R-Ky., needs at least six Democrats to join all 54 Republicans to approve a motion clearing the bill for final passage in the 100-member chamber.

The Senate’s top Democrat, Harry Reid of Nevada, said last year that was not going to happen. Even if it did, President Barack Obama has pledged to veto the bill if it gets to him.

The upshot may be more of the same on Capitol Hill: A war of words, with Republicans blasting Obama for failing to do what they see as necessary to secure the United States and Democrats accusing the GOP of fear-mongering to score points with voters.

The legislation would order FBI background checks for Syrian and Iraqi refugees and require that the FBI, Homeland Security Department and the director of National Intelligence certify that each refugee is not a security threat. The bill’s requirements would effectively suspend admissions of Syrian and Iraqi refugees.
