Other than the mandatory audits of publicly financed Presidential campaigns and national party convention committees, Section 438(b) of the Federal Election Campaign Act (FECA) allows the Commission to audit a committee if its reports do not meet the threshold require- ments for substantial compliance with the Act. Campaign Finance Analysts in the Commis- sion’s Reports Analysis Division (“RAD”) review every report following detailed procedures approved by the Commission. If questions arise concerning a committee’s compliance with the FECA, the analyst may send the committee a Request for Additional Information (“RFAI”) Letter which is made available to the public.
