LANSING, MI (AP)-- Republican U.S. Senate candidate Pete Hoekstra's campaign has filed charges with the Federal Elections Commission over an independent political action committee that's running TV ads attacking him.
Hoekstra's campaign says Prosperity for Michigan acted illegally when it didn't disclose donors in its quarterly report and then filed an amended version on Monday, the day it began airing the ads.
Several Detroit-area business executives who support Hoekstra's GOP rival Clark Durant are funding the PAC. It's spending $275,000 to air ads before the Aug. 7 primary election.
The ads criticize Hoekstra for voting for earmarks and raising the federal debt ceiling while he was in Congress through 2010.
Hoekstra, Durant and Randy Hekman are competing in the Republican primary for the chance to take on Democratic incumbent Debbie Stabenow in November.
