The U.S. Senate’s vote on healthcare reform legislation will be pushed back a least a week as a key committee waits on the Congressional Budget Office’s report on the cost of the measure, the Wall Street Journal reported.

That means debate on the Senate floor won’t happen by Oct. 12 as originally planned. The finance panel expects the CBO report “later this week,” a congressional aide told the newspaper, delaying its final vote on the measure as well.

Although there’s debate within the Democratic majority and between Dems and Republicans over just about every aspect of the proposed reforms, there’s also a growing, bi-partisan movement in support of some form of overhaul.

California Gov. Arnold Schwarzenegger, a Republican, today urged passage of some type of healthcare reform measure, arguing that his state’s goals and those of President Barack Obama are the same — driving down costs and promoting an economic recovery.

And former Republican leaders are also coming out in favor of reform, although perhaps not as vigorously as some of their Democratic counterparts.

Former Senate majority leader Bill Frist and former Health and Human Services secretary Tommy Thompson each suggested that they would support the legislation, with some reservations, and New York City Mayor Michael Bloomberg, an independent, has said the bill is “shaping up to merit broad, bipartisan support,” according to the Journal.
