TRENTON - New Jersey's campaign law enforcement agency says former Democratic candidate for governor and state Sen. Barbara Buono violated state law by failing to establish separate committees in 2013.

The Election Law Enforcement Commission said Wednesday Buono's senatorial committee hired a firm in January 2012 to poll voters on her prospects as a gubernatorial candidate.

The document says she established her gubernatorial campaign committee in December 2012. It also states she filed a form for her gubernatorial candidacy 312 days late.

The document also notes she reimbursed her senate committee from her gubernatorial account in 2014 for the same amount spent on polling in January 2012.

Buono lost to Republican Gov. Chris Christie in 2013.

She was not immediately available for comment.
