Treasury Secretary Steven Mnuchin and Senate Majority Leader Mitch McConnell are headed to Fort Knox to see its gold hoard first hand.

Mnuchin announced Monday, while appearing with McConnell at a Chamber of Commerce event in Louisville, Ky., that he would tour the bullion depository so that he could personally attest that the roughly $200 billion worth of gold there is part of the government's assets.

"I assume the gold is still there," Mnuchin said.

"We're going to find out," McConnell joked.

"It would really be quite a movie if we walked in and there was no gold," Mnuchin added.

The status of the government's gold at Fort Knox is sometimes the subject of speculation and conspiracy theories. The stores are reviewed by the U.S. Mint, and the Treasury reports that the government has 147 million ounces of gold stored there.

But the vaults are not often visited by high-ranking officials. Mnuchin said Monday that he would be only the third treasury secretary to visit. He pointed out that the last time that members of Congress visited Fort Knox was 1974.
