WASHINGTON (AP) — The Senate is set to consider new rigorous screening procedures for Syrian and Iraqi refugees seeking to enter the United States. The measure is coming up at a time when national security looms large for voters in an election year.

The legislation has gained momentum as a result of the Islamic State group’s attacks in Paris.

The GOP-backed proposal 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.
