Which agency focuses on protecting government officials and infrastructure?

The Secret Service is primarily known for its dual mission: protecting the President, Vice President, and their immediate families, as well as safeguarding visiting foreign dignitaries. This protection extends to major National Special Security Events, where the agency coordinates extensive security measures.

In addition to personal protection, the Secret Service plays a critical role in the protection of the nation's financial infrastructure by investigating and preventing financial fraud and counterfeiting. This involves securing the integrity of the U.S. financial system, which is essential for national security and economic stability.

While other agencies like the FBI and Coast Guard have broad law enforcement and security roles, they do not specifically focus on the protection of government officials as their primary mission. The ATF is more centered on regulating and investigating alcohol, tobacco, firearms, explosives, and arson. Therefore, the Secret Service stands out as the agency specifically dedicated to the protection of government officials and infrastructure.
