Steven A. Sund (born 6 April 1972) is a retired American law enforcement official, author and public speaker.

A December 2024 interim report by the Subcommittee on Oversight of the 118th Congress concluded that Sund had “unfairly shouldered the bulk of the blame” and highlighted systemic failures across federal agencies.

[1] Sund received a BS and MS from Johns Hopkins University, and an MA in homeland security from the Naval Postgraduate School.

Sund authored many of the special events manuals for the District of Columbia and helped shape the Department of Homeland Security's National Response Framework.

He also has instructed the U.S. Secret Service in major events planning and has taught Incident Command System as an adjunct professor at the George Washington University.

[2] Sund was chief when, on January 6, 2021, rioters stormed the U.S. Capitol building while Congress was counting the electoral votes of the 2020 presidential election.

[13] Toward the end of the letter, Sund acknowledged a breakdown in some systems, which he argued could nonetheless be rectified through provision of resources, training, updates to policy, and accountability.

He argued that intelligence officials were responsible for the Capitol attack, and that they had neglected to properly share warnings about the potential of the event becoming violent.

Republican members of the subcommittee indicated they felt Sund received disproportionate blame for the attack on the Capitol from political figures including Pelosi.

The bipartisan report concluded that former Capitol Police Chief Steven Sund had “unfairly shouldered the bulk of the blame for the security failures of that day.” It emphasized that Sund’s reputation had been unjustly maligned in the immediate aftermath but was “restored” through the subcommittee’s investigation, which uncovered systemic failures and miscommunications across agencies, including the Pentagon and the D.C. National Guard.
