Mike Spence, chief of staff for Republican Assemblyman Curt Hagman of Chino Hills, says the last of the refund checks was mailed Wednesday.

The three organizations - the Buddhist Temple of Chino Hills, the Bu-Sha Center and Buta Buddhism Research Center, both of West Covina - gave Hagman campaign donations despite their nonprofit status. That prohibits them from becoming involved in political campaigns.

Representatives of the temples say they did not know the contributions were illegal.

Hagman says he was unaware of the temple contributions until they were pointed out to him by The Associated Press.
