The U.S. Secret Service, created in 1865 to root out counterfeit currency, has seen its protective mission swell far beyond its original mandate. Today, under the Former Presidents Act of 1958, the agency operates a security apparatus that shadows former presidents and their spouses, funded by an annual budget of approximately $2.8 billion and staffed by more than 7,000 personnel.
That force dedicates itself to physical security, intelligence monitoring, and counter-surveillance. But the quiet escalation of protections around former President Donald Trump reveals how dramatically the threat landscape has shifted in recent years, moving from state-sponsored plots to individual actors.
A Quiet Escalation Since 2020
The turning point arrived in 2020. Following the U.S. assassination of Iranian General Qasem Soleimani and subsequent Iranian threats, the Secret Service increased security for Trump, who was then still in office.
That enhancement marked the beginning of a pattern that would intensify two years later. In 2022, the revelation of a plot to assassinate former National Security Advisor John Bolton sent another jolt through the protective detail. The Secret Service again enhanced security for Trump.
The Bolton plot underscored a grim reality: former U.S. officials, particularly those who served in the Trump administration, had become targets. The agency does not publicly confirm threat assessments against specific protectees.
But the pattern of enhanced security measures tells its own story. Trump himself has framed the threat in stark personal terms. In 2024, he claimed to be the “No. 1 target,” a statement that reflects the security reality the Secret Service has been grappling with for years.
Physical security at Trump’s properties has been upgraded. The intelligence division tracks chatter across open-source and classified channels.
Counter-surveillance agents sweep routes and venues before any movement. The machinery of protection grinds on, invisible to most Americans but ever-present to those inside the bubble.
A Mission Rooted in Law and Adaptation
The Secret Service’s protective mission is rooted in law, but its execution is a matter of constant adaptation. The agency operates under the Department of Homeland Security. Its origins date to 1865, when the first mission focused on stopping the counterfeiting of U.S. currency.
Because of this focus, the agency remained part of the Department of the Treasury for over a century. The mission expanded in 1901 when the agency began protecting presidents and presidential candidates.
Today, the agency manages two primary national security tasks. One involves safeguarding the financial and critical infrastructure of the country. The other ensures the safety of the president, vice president, and their families, and extends to former presidents and their spouses.
These duties are significant because they secure the stability of the executive branch. The agency must adapt its methods to meet evolving threats against high-ranking officials.
The 2020 shift after the Soleimani assassination and the 2022 Bolton plot are recent examples of that adaptation. Each event forced a reassessment of risk and a corresponding upgrade in protective posture. The scale of the challenge has shifted dramatically, demanding a force of more than 7,000 personnel and a budget of $2.8 billion to keep pace.
The Secret Service does not publicly detail the specific intelligence that drives its decisions on former presidents, but the visible increases in security–upgraded physical barriers at properties, expanded counter-surveillance sweeps, heightened monitoring of threat chatter–demonstrate an agency that is continuously recalibrating to meet a threat environment that includes both state-sponsored actors and individual malefactors. This work ensures that leadership remains secure from physical harm and foreign interference.
The protective posture around former President Trump, tightened for years through a quiet but constant escalation, reflects the broader reality that the Secret Service must remain vigilant not only for sitting presidents but for those who have left office. The pattern of enhanced measures, from 2020 onward, illustrates an agency that has had to evolve its methods in response to a changing world, all while operating under a legal mandate that dates back to the years after the nation’s founding.
