The investigation of petition fraud by former Congressman Thaddeus McCotter has widened to include two earlier campaigns.
Republican Thaddeus McCotter quit his job last month after the Michigan Secretary of State's office found most of the 1800 signatures on his nominating petitions had been copied and pasted.
Now a review finds many of McCotter's 2008 and 2010 petition pages were doctored.
Political consultant Rich Robinson thinks McCotter knew about the fraud.
"I find it impossible to believe that he was unaware of what was going on," Robinson says. "I guess there's plausible deniability there, but I'm not convinced."
The Michigan Attorney General's office says prosecution isn't likely because the statute of limitations has expired for the two earlier campaigns.
Charges been filed against five former staff members in the current case.
