(CNN) – U.S. Rep. Thaddeus McCotter said Saturday that he is ending his write-in bid for re-election, within a week of announcing he would not be on the primary ballot and requesting an investigation to determine why many of the signatures on his petition were ruled invalid.
"One can't clean up a mess multi-tasking," the Republican from Michigan said in a statement. "Honoring my promise to the sovereign people of our community only allows me to finish the official duties of my present congressional term; and aid the State Attorney General criminal investigation that I requested into identifying the person or persons who concocted the fraudulent petitions that have cost me so dearly."

The state attorney general's office on Thursday said it would "investigate allegations of possible fraud" into the irregularities pointed out by the state's elections bureau, which included "duplicate signatures and the appearance of altered petitions."
McCotter used an analogy to "It's A Wonderful Life" to describe his ballot misfortune in an op-ed published Tuesday in The Detroit News.
"Now I feel like George Bailey after Uncle Billy admitted he lost the money," he wrote. "Like George, knowing my misplaced trust has negatively impacted so many people is heartrending. Unlike George, I am not tempted to jump off a bridge."
In the Saturday statement, McCotter did not say if he would consider running for Congress or another office in the future. He is currently serving his fifth term and briefly sought the Republican presidential nomination.
