Update (5:15pm): The puzzle, wrapped in an engima, inside a bag of blow surrounding the "mystery" cocaine found in the White House is drawing in some of the world's most cunning detectives and brilliant minds.

One day after leaked radio intercepts revealed that a "mystery" substance was found over the weekend inside the White House and - after leading to a brief evacuation over hazmat fears - was "cocaine like", the US Secret Service on Wednesday confirmed what everyone already knew - the powdery substance found inside the White House over the weekend is cocaine.

While little new was revealed, secret service spokesman Anthony Guglielmi said that the cocaine was discovered in an area of the West Wing lobby where individuals can store their phones.
