WASHINGTON (AP) — House Republicans unveiled a bill Friday renewing the Social Security payroll tax cut and extending but trimming unemployment benefits but barreled toward a showdown with President Barack Obama by including language jumpstarting work on a controversial oil pipeline.

With Democrats claiming the measure is too stingy toward jobless and lower-income people, next week's House vote looms as the opening scuffle in a year-end battle that will let each party spotlight its economic priorities ahead of November's presidential and congressional elections.

The two parties generally agree on the bill's pillars: preventing the Jan. 1 expiration of payroll tax cuts and of extra coverage for the long-term unemployed, and avoiding a mandated cut in payments the government sends doctors for treating Medicare patients.
