WASHINGTON (AP) — The Federal Election Commission has fined a political action committee associated with Democratic presidential candidate Bernie Sanders for missing financial reporting deadlines. The Vermont Press Bureau reports that the FEC in December sent a letter to the Progressive Voters of America Leadership PAC warning about the missed deadlines. The PAC's treasurer responded in May by acknowledging it had neglected to file the reports, calling the lapse "an inadvertent mistake." The PAC paid $7,690 in fines to the FEC. The press bureau obtained copies of the correspondence, which it reprinted on its website.
