PASSAIC - A New Jersey mayor up for re-election is under fire for allegedly failing to report his campaign finances.

Alex Blanco has been the mayor of Passaic for four years, but has not been filing those reports consistently.

The state Election Law Enforcement Commission (ELEC) requires this information to be filed every 90 days. But records show Blanco failed to file 14 spending reports from 2009 to 2012.

Blanco calls it an oversight, blaming it on a treasurer, and says the issue is being resolved. His campaign office submitted the missing reports in April, but the commission says the mayor could face fines of more than $200,000.

In addition, some of the newly filed reports show other serious issues. There were at least five checks, including one for $5,000, that were written directly to Blanco. Under the law, candidates can only be repaid if they lend money to their own campaigns, which Blano did not.

Jose Sandoval, one of Blanco's opponents, has asked ELEC to launch a formal investigation.

Blanco says that despite these challenges, he expects to win re-election next week.

"My record talks for itself,” he says. "I believe this is one issue, and I should be judged by the four years I served as mayor."
