Sen. John McCain says he can't vote for the GOP's Graham-Cassidy health care bill

Senator John McCain said on Friday that he would vote against a new Republican bill to dismantle Obamacare if it is brought onto the Senate floor next week, in a new setback for the proposal.

"I cannot in good conscience vote for the Graham-Cassidy proposal," the Arizona senator said in a statement about the bill sponsored by Senators Lindsey Graham and Bill Cassidy. "I believe we could do better working together, Republicans and Democrats, and have not yet really tried. Nor could I support it without knowing how much it will cost, how it will effect insurance premiums, and how many people will be helped or hurt by it. Without a full CBO score, which won’t be available by the end of the month, we won’t have reliable answers to any of those questions."
