According to Fox News, Warren's campaign treasurer, Albert Jones Jr., and the treasurer of her PAC, Rosalind Brooks-Harris were also charged.
Warren has not been arrested, but will be processed according to Monroe County District Attorney Sandra Doorley. If convicted, the mayor would be removed from office.
"This could be a long process and we anticipate that there could be challenges along the way so I don't think this will be anything resolved quickly," said Doorley in a press briefing.
Warren has called the investigation a "political witch hunt." Her lawyer did not return messages from Fox News seeking comment.
Specifics about the ongoing investigation were not revealed but the charges focused on Warren's first term in office from November 2013 through November 2017 in which she raised hundreds of thousands of dollars for her re-election, RochesterFirst.com reported.
Doorley said the city's first female mayor and others took steps to evade contribution limits. -Fox News
