Governor Jon Corzine?s (D-NJ) office received a subpoena from the U.S. Attorney?s Office Wednesday for its budget documents.

The subpoena is the latest in a round of subpoenas from federal investigators looking into the state?s budget development since 2004. A Corzine spokesman says the records requested from the governor?s office span the administrations of Democrats James McGreevey, Richard Codey and Corzine.

On February 16, the U.S. attorney subpoenaed documents from legislative leaders and their staff offices. Federal investigators were seeking information on grants that have been placed in the budget without public review just before the budget is adopted.
