The Secret Service Can't Determine Who Brought Cocaine to the White House

Claim: The Secret Service is unlikely to identify the person who left a bag of cocaine at the White House over the weekend.

Who said it: Politico, citing an unidentified law enforcement official "familiar with the investigation."

Context: One of the most secure buildings in the world was temporarily evacuated Sunday following the discovery of a small bag of cocaine on the premises. The Secret Service said Wednesday an investigation is underway to find the culprit. But an anonymous source with knowledge of the probe is working the press to temper public expectations that the fugitive will ever be found.
