McCotter, who found himself in the position of running a write-in campaign after failing to get enough petition signatures to get his name on Michigan's primary ballot, said he would finish out his current turn and assist the state attorney general's "criminal investigation that I requested into identifying the person or persons who concocted the fraudulent petitions that have cost me so dearly," McCotter said in a statement posted on his campaign Web site.
"One can't clean up a mess multitasking," said the 46-year-old, five-term representative from Michigan's reliably Republican 11th District, which includes Detroit's northwestern suburbs.
"To those who unhappy at this news, I'm sorry; to those happy at this news, you're welcome," McCotter concluded.
