On Thursday, Senate Republicans tried to push the issue to the chamber floor, attempting to offer an amendment to the pending transportation bill that would have overturned the new rule. Senate Majority Leader Harry Reid, Nevada Democrat, blocked the move.

But the issue is likely to come up again, and even some Senate Democrats — particularly those up for election this year — say the policy should be revoked.

In the GOP-controlled House, Speaker John A. Boehner of Ohio said he and fellow Republicans are already working on legislation to undo the ruling.

“We’re going to handle this openly and deliberately so that every lawmaker can have their say and the voice of the people can be heard,” said Mr. Boehner at the CPAC gathering. “One thing’s for certain. This attack on religious freedom cannot and will not stand.”
