BREAKING: MTG SLAMS Biden WH for giving up on cocaine investigation

On Thursday, the Secret Service held a briefing wherein it announced that the investigation into the cocaine found at the White House would be concluding without determining to whom it belonged.

The news was met with criticism from many, including Rep. Marjorie Taylor Greene, who said she wasn't buying the Biden administration's excuses. The Georgia congresswoman called the investigation a "total failure."

"Just speaking with the Secret Service now," Greene began after a private Secret Service briefing, "they were able to narrow down a list of approximately 500 people that had left a small bag of cocaine in a cubby ... Have they drug tested this list of 500 potential suspects that brought an illegal substance, a drug, cocaine, into the White House?"

Greene stated that the Secret Service had said, in no uncertain terms, that such tests would not be administered.

"It makes no sense to me whatsoever why they would not follow through on one simple task," she added. "The American people, every single day, go through drug tests to do a job."

She slammed the Biden administration for holding everyday Americans to a different standard than the elected officials and government bureaucrats whose salaries are paid for with their tax dollars.

"This was a failure of this investigation," Greene said of the Secret Service's refusal to perform drug tests.

A powdery substance was first discovered in the heavily trafficked West Wing of the White House on July 2, and by July 5, officials had confirmed that it was, in fact, cocaine.

At the time it was discovered, the first family, including Hunter Biden, were out of town from Friday to Tuesday, leading to speculation regarding who could have left it there. A specific time at which it had likely been discarded was not determined.

As Politico& reports, an unidentified source familiar with the case said it would be "be very difficult" to detect the perpetrator "because of where it was," noting that the baggie was discovered in a surveillance camera blind spot.

"Even if there were surveillance cameras, unless you were waving it around, it may not have been caught," the source said. "It's a bit of a thoroughfare. People walk by there all the time."

On Wednesday, Fox News' Jesse Watters announced that he had filed a FOIA request to obtain tapes from cameras in the area that day.
