The comptroller general reached out to all 10 departments and agencies that indicated they had contracts with McKinsey & Company and provided them with an audit program that the internal audit shop had to, at a minimum, carry out, in addition to whatever other work they may have wanted to do around the procurement process. Every department's internal audit shop is supposed to be independent of the organization and reports directly to the deputy head on what they find when they do audit work within the department or agency.
