Des Moines Register: An animal abuse complaint against Iowa state Sen. Ken Rozenboom, an Oskaloosa-area pork producer targeted by an animal rights group for his role in passing the state's new "ag-gag" law, is unfounded, say state and local investigators. "The investigation did not indicate there was any abuse," said Mahaska County Sheriff Russell Van Renterghem, who worked with County Attorney Andrew Ritland in reaching the conclusion. Direct Action Everywhere, a California-based animal rights group, filed the complaint against Rozenboom after entering one of his pig facilities without permission in April, taking photographs and video of the animals inside.
