Several Senate Democrats up for reelection tell The Hill they haven't ruled out bucking President Obama by voting to repeal the health law's cost-control board.

The House is expected to repeal the Independent Payment Advisory Board next week, putting pressure on the Senate to follow suit. While the bill has broad bipartisan support in the House, no Senate Democrats have so far signed onto repeal legislation despite coming under increasing pressure to do so.

"We're looking at it, let's put it that way," said Sen. Joe Machin (D-W.Va.). "We'll weigh the pros and cons" if the bill hits the floor.
