The White House was evacuated after the secret service found cocaine inside.

The «suspicious substance» was discovered Sunday evening by uniformed security personnel time for a scheduled inspection of the building.

The discovery of the substance prompted the evacuation of the executive mansion and the closure of nearby roads.

President Biden was not at the White House at the time of the discovery, having spent the weekend at Camp David.

Gunpowder was found in the work area of ​​the West Wing and was initially assessed by the fire department.

After it was found to be a non-hazardous sample, it was sent to a lab for testing by the Secret Service.

Preliminary tests on a small amount of the white powder showed it to be cocaine. Exactly where the drug was found in the building was not reported.

There were unconfirmed reports that it was found in the White House Library, which is part of the official visitor tour and three floors below the First Family's living quarters.

He added that the «cause and method» of how the substance got into the White House was being investigated.

Details of the discovery appeared on openmhz.com, a site that allows listeners to eavesdrop on emergency services.

On Sunday at 8:49 p.m., a firefighter said: «We have a yellow bar that says 'cocaine hydrochloride.”

Cocaine hydrochloride is different from “street cocaine.”

Cocaine hydrochloride, which comes as a white powder, is used as a local anesthetic and is also inhaled by drug addicts. However, it is different from «street cocaine.»

Conservative websites were quick to point out that Hunter Biden, the president's 53-year-old son who admitted to struggling with addiction, was in the White House in time.

But there was no evidence linking it to the presence of the drug that was found in the mansion.

Others have speculatively tried to link the discovery to White House personnel or even members of the press.

The The Telegraph has reached out to the White House for comment.
