The White House was evacuated Sunday evening after the Secret Service discovered suspicious powder in a common area of the West Wing, and a preliminary test showed the substance was cocaine, two law enforcement officials said Tuesday.
President Joe Biden had recently left for Camp David, where he was joined by his troubled son Hunter who has a long history of drug abuse.
Secret Service agents were doing routine rounds on Sunday when they found the white powder.
It was found in an area accessible to tour groups, not in any particular West Wing office, the officials claimed.
The complex was evacuated at about 8:45 p.m. Sunday as fire and emergency crews were brought in to do a rapid test, which preliminarily identified cocaine. The White House was soon reopened and the powder was sent for further testing.
Biden and his family left for Camp David on Friday and returned to the White House on Tuesday.
The Secret Service said in a statement the White House was closed as a precaution as emergency crews investigated, and that the District of Columbia fire department was called in to evaluate and determine that the substance was not hazardous.
“The item was sent for further evaluation and an investigation into the cause and manner of how it entered the White House is pending,” the Secret Service said.
