The Senate voted Tuesday to begin debating a replacement for the Affordable Care Act. It remains uncertain as to what that replacement might look like. No formal legislation has been drafted. But senators moved to take the procedural first step, known as a "motion to proceed." The vote was 51-50, with Vice President Pence casting the tiebreaking vote.
Debate will now begin, most likely on a measure to fully repeal the law, also known as Obamacare.
