Rep. Michael Grimm has vowed to stay in office after he pleaded not guilty Monday to a 20-count federal indictment that includes charges of mail fraud, wire fraud and tax fraud.
The House Ethics Committee announced in 2012 that Grimm was under investigation for possible campaign finance violations. That committee said it would defer its inquiry because of a separate Department of Justice investigation.
According to the committee, the Staten Island Republican may have violated campaign finance laws by soliciting and accepting prohibited contributions. That may have led to false information being included in campaign finance reports, the committee said.
