DES MOINES, Iowa -- Des Moines police will start a criminal investigation Thursday into the secret taping of a private U.S. Senate campaign meeting for Greg Ganske, meanwhile the person who made the tape is agreeing to cooperate with authorities.

Officials with the Polk County Attorney's office said there was enough evidence to proceed with a formal investigation. Ganske is running against incumbent Sen. Tom Harkin.

This harkins back to the days of watergate.
