Trump to inspect Fort Knox: US President Donald Trump on Friday said that he will inspect the country’s top gold reserve facility, Fort Knox, to make sure that it has 400 tonnes of gold. Fort Knox is an important location in the US, as it has been a site of America’s maximum gold reserves since 1937. Fort Knox is located in north-central Kentucky, and its Bullion Depository’s vaults are home to 147.3 million ounces of gold, which is more than half of the Treasury Department’s gold reserves, according to a report by NY Post.
