A county prosecutor has begun a criminal investigation to determine whether a staffer for Republican John Thune violated the law in securing absentee ballots.

Jeff Thune, who is John Thune's nephew, allegedly processed absentee ballot applications at a university. But since he is not a certified notary public, the state is concerned.

Thune's campaign says Jeff didn't do anything wrong. Absentee ballots could be voided if they were not notarized properly.
