Edwards is out with a new ad Tuesday.
WASHINGTON (CNN) - New York Sen. Hillary Clinton's presidential campaign called a new television ad released Tuesday by former North Carolina Sen. John Edwards "unconstitutional gimmickry."
In the commercial airing in Iowa, Edwards promised to end congressional health care benefits if they fail to pass a universal health care plan within six months of his administration.
"There’s no excuse for politicians in Washington having health care when you don’t have health care," Edwards said in the ad.
But Clinton's campaign pointed out on its Web site that this proposal is unconstitutional. The Clinton campaign said it would violate the 27th amendment, which states that any law to change the compensation of members of Congress has to be approved by the House.
Edwards' Communications Director Chris Kofinis said the Clinton campaign’s response shows that she wouldn't fight to pass universal health care.
"Today, Senator Clinton made it crystal clear where she stands: she defends health care for politicians while millions of Americans and their families go without care," Kofinis said. "Voters have a clear choice between John Edwards, who will fight to finally pass universal health care, and Senator Clinton, who seems intent on defending the Washington establishment."
