Scott Brown in USA Today

On Corporations: AdWatch: Loosened financial reform regulations

The ad, which the PAC says will run for 10 days, hits Brown for successfully supporting the elimination of fees on banks in the Dodd-Frank financial reform regulation of 2010 and for supporting exceptions to the "Volcker rule," which prohibits banks from making certain investments with their capital.

Brown "delivered for Wall Street, saving big banks $19 billion in taxes,'' the ad says, and "wrote legislation that would help big banks make risky investments. That's good for Wall Street and great for Scott Brown, but it doesn't make sense for New Hampshire.''

The ad also calls Brown "the senator from Massachusetts'' three times, just in case anyone in New Hampshire has forgotten.
