WASHINGTON (AP) — Republicans are dropping their demands for additional spending cuts and will hold a House vote on whether to give final congressional approval to the Senate-approved compromise averting "fiscal cliff" tax increases and spending cuts.

The House vote was expected Tuesday evening.

A decision by the Republican-run House to amend the Senate-passed bill would have complicated prospects for final congressional passage of the measure. Senate Democratic aides have said the Democratic-led Senate, which overwhelmingly approved the compromise early Tuesday, would not return to vote on an amended version of the measure.

The measure would allow tax increases on the highest-earning Americans, but retain decade-old income tax cuts for everyone else.
