KEY POINTS
  • Senate votes 51-50 to start debate on Obamacare repeal, with Vice President Mike Pence casting a tiebreaking vote.
  • Passing the motion to proceed does not mean Republicans have a consensus on a bill they can pass.
  • Sens. Susan Collins of Maine and Lisa Murkowski of Alaska voted against the motion.

The Senate on Tuesday voted by the narrowest margin to move forward with its Obamacare repeal push, a significant step for Republicans that still leaves senators searching for an agreement on how best to follow through on a campaign promise that has defined most of the last decade.

Vice President Mike Pence was forced to break a tie as the Senate voted 51-50 to start debate on proposals to change the landmark health-care law. The vote comes after weeks of setbacks for Republicans as party divisions stalled multiple versions of their plans to overhaul the American health-care system.
