BOSTON (AP)- A former Republican U.S. attorney for Massachusetts who also ran for heard of the state GOP is calling for an investigation into Democrat Elizabeth Warren's law license, echoing a charge also raised by Republican U.S. Sen. Scott Brown.
Warren, a Harvard Law School professor, said McNamara is "just wrong." Democrats accuse Brown of mudslinging.
Warren and Brown are locked in a tight U.S. Senate race.
Francis McNamara, who resigned in 1989 after federal investigators concluded he'd falsely accused former GOP Gov. William Weld of smoking marijuana, said the Massachusetts Bar of Board Overseers should investigate whether Warren "engaged in the unauthorized practice of law."
McNamara argues that because Warren was never admitted to the Massachusetts bar, some of her work may have violated the state's rules of professional conduct for attorneys.
Warren said she's always followed the rules.
"I'm a member of the bar of Texas. I was a member of the bar of New Jersey. I'm a member of the United States Supreme Court bar, I'm a member of several federal bars," Warren said Monday.
"I have always complied with the rules of court whenever I have appeared. Always," she added.
Michael Mone, a lawyer and former president of the Massachusetts Bar Association and former member of the Board of Bar Overseers, said McNamara has it wrong and that Warren broke no rules.
"She is so clearly covered by the applicable rules. To argue to the contrary is silly," said Mone, who is also a Democrat.
McNamara resigned as U.S. Attorney after making unsubstantiated charges that Weld, also a former federal prosecutor, had smoked marijuana at a party. McNamara later acknowledged smoking marijuana himself.
Massachusetts Democratic Party Chairman John Walsh called on Brown to "stop the mudslinging."
