The presence of cocaine at the White House prompted a flurry of criticism and questions from Republicans, who requested a briefing Thursday on the probe. White House press secretary Karine Jean-Pierre said President Joe Biden believed it was “incredibly important” for the Secret Service to get to the bottom of how the drugs ended up in the White House. The Secret Service is responsible for securing the White House and led the investigation. Anyone who comes through the White House must give identifying information and pass through security before entering. White House staff are fingerprinted; participants in tour groups are not.
