The White House remains confident in the Secret Service's ability to secure the executive campus, despite not being able to identify a suspect in its cocaine investigation.

White House press secretary Karine Jean-Pierre underscored President Joe Biden's continued confidence in the protective agency, which he privately expressed concerns with after the events of January 6, 2021.

Jean-Pierre described the Secret Service's investigation into the cocaine, which was found in a cubby in the West Wing, as "thorough." She added that "hundreds of visitors" are processed in the lobby area where the substance was discovered.

"We're not going to opine on the investigation," she said Monday.

The Secret Service concluded its investigation last week with no suspects after combing through visitor logs and security footage.

"There was no surveillance video footage found that provided investigative leads or any other means for investigators to identify who may have deposited the found substance in this area," the Secret Service said last Thursday. "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."
