Subdued House Republicans Tuesday evening resigned themselves to passing the Senate's "fiscal cliff" bill, backing away from threats earlier in the day to amend the deal with cuts.

The GOP called a hearing in the Rules Committee on the Senate measure, which is a precursor to holding a vote.

After their second conference meeting of the day, lawmakers said they were likely to punt on launching a fresh showdown with the Democratic-led Senate. Many appeared to concede that the end result would be an up-or-down vote on the Senate-passed fiscal cliff deal without any amendments. At least one lawmaker added his belief that with House Democratic support, the bill would end up making it into law.
