WASHINGTON, July 5 (Reuters) – Cocaine discovered in the White House on Sunday was found in a cubby hole in a West Wing entry area where visitors place electronics and other belongings before going on tours, a source familiar with the matter said on Wednesday. The Secret Service is investigating the matter, the White House said. “They’re checking visitor logs and … looking at cameras. Those are the next steps. Cross-checking,” said the source. White House spokesperson Karine Jean-Pierre told reporters: “Where this was discovered is a heavily traveled area where many … West Wing visitors come through.” Asked whether anyone had undergone drug testing as part of the investigation, Jean-Pierre said: “We will take any action … that is appropriate and warranted, pending the outcome of Secret Service.” Possession of cocaine, which is classified as a “schedule II” drug under the U.S. Controlled Substance Act, is a misdemeanor in Washington, D.C. The West Wing is attached to the executive mansion where President Joe Biden and first lady Jill Biden live. It includes the Oval Office, cabinet room and work space for presidential staff. Hundreds of people pass through the West Wing on a regular basis, including political staff, their guests and members of the press. Jean-Pierre said West Wing tours took place on Friday, Saturday and Sunday. The substance was found during a routine Secret Service sweep on Sunday evening. A Secret Service spokesperson did not respond to requests for comment on Wednesday. The agency has not said how much cocaine was found.
