WASHINGTON (AP) — Democrats launched a drive at both ends of the Capitol on Wednesday to strip the insurance industry of its decades-old exemption from federal antitrust laws, part of an increasingly bare-knuckled struggle over landmark health care legislation sought by President Barack Obama.

If enacted, the change would put an end to “price-fixing, bid-rigging and market allocation in the health and medical malpractice” insurance areas, said Sen. Patrick Leahy, D-Vt., chairman of the Senate Judiciary Committee. Leahy said he would seek a vote on the plan when the Senate debates health care legislation in the next few weeks.
