Sen. Bill Cassidy says he's working with White House on lowering health care costs

Sen. Bill Cassidy, chairman of the Senate health committee, told "Face the Nation" moderator Margaret Brennan that Republicans are "absolutely in communication with the White House" regarding a proposal to give Americans cash to "purchase health care on their own terms." Congress is expected to vote in December on extending health insurance tax credits that are set to expire at the end of the year.
