The White House is encouraging Senate Majority Leader Harry Reid (D- Nev.) to cut a deal with Sen. Joe Lieberman (I-Conn.), which would mean eliminating the proposed Medicare expansion in the health reform bill, according to an official close to the negotiations. Lieberman threw health care reform into doubt Sunday when he told Reid that he would filibuster the bill if it allowed Americans ages 55 to 64 to purchase coverage in Medicare.
