Every White House employee should be tested for cocaine after the U.S. Secret Service closed the investigation due to a lack of physical evidence, Sen. Tommy Tuberville said Thursday.

The baggie of cocaine, discovered by the Secret Service earlier this month inside a receptacle used to temporarily store electronics in a White House lobby, was analyzed by an FBI lab. But the results, which revealed the then-unknown substance was cocaine, did not develop latent fingerprints and contained “insufficient DNA,” the Secret Service said earlier Thursday.

“Therefore, the Secret Service is not able to compare evidence against the known pool of individuals,” the agency said.

Meanwhile, there was no surveillance footage video that could generate leads, according to the Secret Service.

“Without physical evidence, the investigation will not be able to single out a person of interest from the hundreds of individuals who passed through the vestibule where the cocaine was discovered,” the Secret Service said. “At this time, the Secret Service’s investigation is closed due to a lack of physical evidence.”

Tuberville called the result “outrageous” in a tweet Thursday afternoon.

“This is outrageous. If they wanted to find the culprit, they could,” the Alabama senator said. “Drug test the entire White House staff right now.”

Rep. Barry Moore, R-Enterprise, called the outcome of the investigation “unacceptable.”

“The White House cocaine investigation lasted less than two weeks and didn’t involve drug testing a single suspect,” he tweeted. “Unacceptable.”
