Has Fort Knox Ever Been Audited?

By GovMint :

Fort Knox has undergone limited audits over history, the last notable being in 1953 and September 1974. The 1953 review was a partial inspection shortly after President Eisenhower took office. In 1974, under the direction of Mint Director Mary Brooks and Treasury Secretary William Simon, a Congressional delegation and press members were invited to view the gold reserves as part of a government transparency initiative. This move marked a rare departure from the strict no-visitor policy, followed by an official audit conducted by the U.S. General Accounting Office and the Department of the Treasury.  In 2017, Treasury Secretary Steve Mnuchin, Kentucky Governor Matt Bevin, and Congressional representatives visited the vaults, marking the first time since 1974 that the vaults were opened to non-authorized personnel.
