Gov. Jon Corzine is catching flack from Republicans for loans he made to his union boss ex-girlfriend.

Corzine's campaign spent much of last week criticizing Republican gubernatorial candidate Chris Christie for not disclosing a $46,000 loan to an assistant U.S. attorney. Republicans are hitting back by bringing up the $470,000 mortgage loan made to Carla Katz.

Like Christie, the governor failed to report his loan on political disclosure forms. He eventually told Katz she didn't have to pay him back.
