Affair over secret documents: Former Trump confidant breaks his silence. Brian Butler was a long-time employee at Trump's private club Mar-a-Lago in South Florida.

Butler is not just another witness in the trial against Donald Trump for embezzling secret government documents. He even helped move relevant files from Trump's residence to his private plane. Trump could actually hold the office of president from prison. However, this would be the first time that a US president has been in prison while in office.
