Democrat Elizabeth Warren has launched two new television ads responding to criticism by Republican U.S. Sen. Scott Brown of her work in an asbestos-related case.

In one ad, Kingston resident Virginia Jackson says her husband died in 1990 from mesothelioma after being exposed to asbestos while working at a Quincy shipyard.

Jackson credits Warren for going ``all the way to the Supreme Court to try to get more money for asbestos victims.'' She says Brown should be ashamed for using victims' suffering to help himself.

Brown has accused Warren of being paid by Travelers Insurance to defend the company against asbestos poisoning settlements and restrict payments to victims.

Brown's campaign also released a new ad faulting Warren for wanting to raise taxes on small businesses, saying it would cost thousands of jobs in Massachusetts. (AP)
