U.S. Sen. Brown, Democrat Warren Spar On Health Care

Republican U.S. Sen. Scott Brown and his chief Democratic rival Elizabeth Warren are trading jabs as the U.S. Supreme Court wraps up three days of arguments on President Obama's health care law.

Warren campaign manager Mindy Myers called Brown's opposition to the law a "reckless" move that threatens health care coverage for young people and seniors and would force the country to return to a time when insurance companies could discriminate on the basis of pre-existing conditions.

Brown campaign manager Jim Barnett said the new law will have a devastating effect on the state's medical device industry beginning in 2013. He said Brown believes the law should be repealed and health care changes left up to the states.

Massachusetts Sen. John Kerry, a Democrat, also defended the law, calling it constitutional.
