Question : Who audits the IRS?
Since other agencies and corporations can get audited by the IRS, I was wondering if someone actually audits the Internal Revenue Service and all their files to make sure they are following procedure and keep accurate records. If so, who does the audit? The Department of Treasury? The CIA?
