Sen. John Ensign (R-Nev.) Tuesday morning raised a constitutional point of order to the health care reform bill over its mandate that all Americans purchase health insurance. Senators are likely to vote on the point of order Wednesday afternoon.“I am seriously concerned that the Democrats’ health reform bill violates the Constitution of the United States of America. As part of comprehensive health reform, the Democrats would require every American citizen to purchase health insurance coverage,— Ensign said in remarks on the Senate floor. “I think that the Congress does not have authority under its enumerated powers to enact such a mandate.—Senate Majority Leader Harry Reid (D-Nev.) and Minority Leader Mitch McConnell (R-Ky.) are negotiating an exact time for the vote.
