In October 2010, the New Hampshire Democratic Party filed complaints with the Federal Election Commission and the Clerk of the House concerning $355,000 Guinta loaned to his own campaign from a bank account that had not been disclosed in any previous financial statements, including those filed during his time as mayor of Manchester. The issue was first raised by Guinta's fellow Republicans during the Republican primary. Guinta dismissed speculation that the money represented an illegal campaign donation, stating that the money came from his own earnings and savings but refusing to make public the related bank statements. On December 15, 2011, the general counsel for the U.S. House Committee on Standards of Official Conduct informed Guinta that the committee reviewed his candidate financial disclosure reports "and subsequent amendments thereto, and have determined that they are in substantial compliance" with federal ethics law.
