MADISON, Wis. (AP) -- Democratic Senate candidate Tammy Baldwin is fighting back against her Republican challenger Tommy Thompson with a new television ad in response to a Thompson spot related to the Sept. 11 attacks.

Baldwin released the ad Wednesday, less than 24 hours after Thompson's spot that questions Baldwin's patriotism for voting against a resolution in 2006 honoring victims of the terrorist attacks.

Baldwin voted for similar resolutions nine times, but didn't in 2006 because the resolution contained endorsements of other Republican policies that Baldwin opposed.

Her response ad begins with a narrator calling Thompson's ad a disgrace. It then attacks Thompson for making $3 million from Logistics Health, a company he led that was criticized for how it handled reimbursements to 9/11 responders under a government contract it won.
