In July 2023, the United States Secret Service found a small plastic bag containing less than a gram of powder cocaine inside the White House.[1] The initial discovery prompted an evacuation of the White House. President Joe Biden and his family were at Camp David in Maryland at the time the cocaine was discovered.[2][3][4] The Secret Service initiated an investigation as to how the cocaine entered the White House.[5] The investigation yielded no forensic evidence and the Secret Service could not narrow below 500 the number of staff or visitors who may have left the cocaine; the investigation was closed after eleven days.[6]
