U.S. Rep. Thaddeus McCotter of Michigan says he's resigning.
The five-term Republican from the Detroit suburb of Livonia said Friday he's leaving office for the good of his family. McCotter dropped his bid for re-election last month after learning his staff hadn't filed enough valid petition signatures to get him on the Aug. 7 primary ballot.
Twice as many signatures as required were turned in, but 80 percent were found to be fake or duplicates.
McCotter says his priorities now are finding another job and helping the state attorney general's office in its investigation of the faulty petition filings.
The 46-year-old attorney ran a little-noticed campaign for the GOP presidential nomination last year before dropping out to seek re-election to Congress.
