MADISON, Wis. (AP) -- Republican Tommy Thompson says he has signed a pledge not to raise taxes on the same day he filed paperwork allowing his U.S. Senate campaign committee to raise and spend money on his behalf.
Thompson said in an email to supporters on Tuesday that he filed his statement of candidacy with the Federal Election Commission. That paperwork was due Tuesday after Thompson last month incorporated his campaign committee.
He has not formally announced his candidacy despite hiring campaign staff, announcing supporters and raising money.
Thompson says he has also signed the Taxpayer Protection Pledge, created by anti-tax crusader Grover Norquist's Americans for Tax Reform. It commits candidates and office holders to oppose all net tax increases.
