McCain to vote for Senate tax reform bill

Republican Sen. John McCain announced his support Thursday for the Senate tax reform bill, boosting the chances for passage of the sweeping legislation.

"After careful thought and consideration, I have decided to support the Senate tax reform bill. I believe this legislation, though far from perfect, would enhance American competitiveness, boost the economy, and provide long-overdue tax relief for middle-class families," the Arizona senator said.

McCain is thought to be a key vote in the effort to pass the tax bill.
