The United States Capitol Police (USCP) said they are launching an investigation after a small bag of cocaine was discovered inside its headquarters.

Police found a “roughly one-inch by one-inch zip lock bag with a small amount of a white powdery substance, which field tested positive for cocaine.”

It was found on the floor inside the Capitol Police headquarters, in an area that’s used for a staging spot for furniture and supplies and is “heavily trafficked” by employees and various contractors, USCP said in a release.

The bag was found by an officer just before 1 p.m. Wednesday and was immediately reported to a supervisor.

USCP headquarters is not at the Capitol, but a few blocks away on D Street and Second Street.

USCP said it has opened an investigation into the incident and will conduct further testing, including DNA testing on the bag.

The Hill has reached out for additional comment from USCP, but the release said they will provide more information when it becomes available.

Last July, the Secret Service confirmed that it had found cocaine at the White House. White House press secretary Karine Jean-Pierre said at the time the cocaine was found in a well-traveled area and that West Wing tours took place in the days prior.

President Biden was not at the White House at the time when it was found. The bag was found near where visitors are asked to leave their cellphones on part of the West Wing tour.
