The precautions

“As a precaution, the White House grounds were evacuated, and the DC Fire Departments Hazmat team responded,” the spokesperson said.

An independent journalist posted photos of a D.C. Fire Department Hazmat truck that responded, as well as crews on the White House complex outside of the West Wing. The photos were posted in the evening, beginning around 7:47 p.m. ET.

Drug-related?

"Now, a newly leaked audio clip reportedly coming from the District of Columbia Fire and Emergency Medical Services Department (DC Fire EMS) has revealed that the previously unknown substance tested positive for Cocaine Hydrochloride, a form of cocaine often used in order to help numb the inside of a nose before a procedure in addition to sometimes being abused for recreational purposes," the Post Millennial wrote.

"US Customs and Border Protection has repeatedly seized cocaine hydrochlorine as it comes into the country. In May, CBP found 5.56 kilos of the drug," it added.

Other recent concerns

"The news comes after a 'Molotov cocktail-style object' was detonated outside three buildings in Northeast D.C." Townhall.com reported.

"While nobody was injured or killed, and it's not clear as to if the two are related, it's still a wild time for both to be happening at the same weekend," it noted.

The incident also occurred after criticisms over first son Hunter Biden traveling with the president to his Delaware home for the past two weekends.

Hunter Biden was recently charged on two counts of tax evasion and one federal firearms charge.

The latest concerns continue to add to controversy as Biden seeks to move forward on his bid for a second term despite already being the nation's oldest sitting president at 80 years old. He would be 86 at the end of a second term, leading to numerous questions about his health and cognitive ability to lead the nation for four more years.
