David Cho is a U.S. Secret Service agent who is the head of the Presidential Protective Division (PPD) detail for U.S. President Joe Biden.[1] Prior to the Biden Administration, Cho served as leader of the PPD detail for President Donald Trump.[2]
Cho is the first Korean-American head of a president's Secret Service detail and has also been described as a perfectionist supervisor.[3][4] Cho was appointed head of Biden's security detail after several agents were removed from Biden's detail over concerns of loyalty to Biden's political rival, Trump.[5][6]
