Mass. Senate hopefuls battle over work histories

Updated:

BOSTON (AP) - Republican U.S. Sen. Scott Brown and Democrat Elizabeth Warren are challenging each other to provide more information about their work histories.

Warren faulted Brown Wednesday for failing to release the names of his clients during his years of public service.

Brown has called on Warren to provide an accounting of her corporate legal clients during her years as a law professor at Harvard University.

Warren said that since she went into public service in 2008, she's made financial disclosures and released her client contacts.

Brown has criticized Warren for her legal work in the 1990s for LTV Steel as it fought mandated health care payments and as a legal consultant for Travelers Insurance in a U.S. Supreme Court case.

Warren made her comments after receiving the endorsement of the Professional Fire Fighters of Massachusetts.
