The Secret Service is carrying out fingerprint and DNA analysis of a bag of cocaine found at the White House to track down its owner.
It comes after the Biden family showed a united front on the Truman balcony for Independence day inviting recovering drug addict Hunter Biden and the rest of the clan to enjoy a dazzling fireworks display.
The dime-sized bag was discovered on Sunday in a cubby hole in the lobby area of the West Wing, where visitors leave their cell phones and other electronics before entering the White House complex.
President Joe Biden and his son Hunter, a recovering cocaine addict, were both at Camp David at the time.
