The Senate has voted to move ahead on health care legislation aimed at dismantling the Obama health law.
The vote was 51-50 on Tuesday, a victory for Majority Leader Mitch McConnell and President Donald Trump. Last week, McConnell was forced to postpone the vote, lacking the support of conservatives and moderates.
Vice-President Mike Pence cast the tie-breaking vote.
In a dramatic turn, Sen. John McCain returned from Arizona where he is battling brain cancer to cast a crucial vote on proceeding on health care.
The vote sets up days of debate and votes on repealing and replacing Barack Obama's health care law. Whatever the Senate approves still requires a vote in the House.
