“Is the gold there?”

As the decades-old question about the legendary Fort Knox makes headlines again, U.S. President Donald Trump is on the hunt for answers.

“We're actually going to Fort Knox to see if the gold is there, because maybe somebody stole the gold. Tons of gold,” Trump said Monday.

His demand for an audit is echoing widely, with public figures like his cost-cutting czar Elon Musk and Republican Senator Rand Paul of Kentucky joining the chorus in recent weeks.
