WASHINGTON (CNNMoney) -- With the price of gold at record highs, presidential candidate Rep. Ron Paul wants to make sure the U.S. gold bars at Fort Knox are really there.

Paul called a congressional hearing Thursday to grill federal officials about his bill to audit and inventory all of the gold reserves at Fort Knox, Ky., West Point, N.Y., and Denver, even though Treasury officials insist that the gold is audited annually and is all there.
