The United States Secret Service has kicked-started the investigation into how cocaine found its way into the White House last Sunday night.
The discovery in the West Wing, which contains the Oval Office and other working areas for presidential aides and staff, led to a brief evacuation.
Secret Service agents found the suspicious powder in an area that is accessible to tour groups while doing a routine inspection. President Joe Biden and his family were at Camp David in Maryland at the time.
A senior law enforcement official told the BBC’s US partner, CBS News, the substance was found in a storage facility routinely used by White House staff and guests to store mobile phones.
The White House complex was closed as a precaution around 20:45 local time (00:45 GMT) last Sunday after it was discovered. A preliminary test later confirmed the substance was cocaine.
The Secret Service will lead a full review of how it got into the White House, officials told CBS. They said cameras and entrance logs would be examined to determine who had access to the area where it was found.
The West Wing is a large, multi-level part of the White House that contains the offices of the president of the United States, including the Oval Office and the Situation Room. It also houses the offices of the vice-president, the White House chief of staff, the press secretary, and hundreds of other staff who have access.
