Senate Minority Leader Mitch McConnell (R-Ky.) slammed the healthcare reform bill released by the Finance Committee on Wednesday, signaling early GOP opposition to the plan.

McConnell asserted that the plan released by Senate Finance Committee Chairman Max Baucus (D-Mont.) was partisan and makes no sense.

"This partisan proposal cuts Medicare by nearly a half-trillion dollars, and puts massive new tax burdens on families and small businesses, to create yet another thousand-page, trillion-dollar government program," McConnell said in a statement. "Only in Washington would anyone think that makes sense, especially in this economy.”

The Baucus bill had been seen as the best effort toward winning bipartisan support for healthcare reform this year, bowing to some Republican demands on abortion funding and coverage for illegal immigrants, in addition to the decision to drop the public (or "government-run") option.

McConnell's statement is an early sign that many Republicans may be unlikely to sign onto the Baucus proposal beyond a handful of centrists who have remained locked in negotiations with members of the Finance Committee and other centrist Democrats.
