The assassination of conservative activist Charlie Kirk at a Utah college has intensified scrutiny of the U.S. Secret Service and renewed questions about its ability to counter an unprecedented level of political threats, security experts said Thursday.
Kirk, 31, was shot in the neck Wednesday while on his “American Comeback Tour” at Utah Valley University and later died. The shooting follows two attempts on former President Donald Trump’s life last year: a July 2024 rooftop attack in Butler, Pennsylvania, in which the shooter grazed Trump’s ear and killed a bystander, and a separate September 2024 incident at Trump International Golf Club in West Palm Beach, Florida, that resulted in the arrest and charging of an alleged assailant. Both attempts remain under investigation and related court proceedings were underway this week.
Former Secret Service agents and security specialists said the agency must adapt quickly to the heightened threat environment even as it balances routine protection duties. Tim Miller, who served as a Secret Service agent under Presidents George H.W. Bush and Bill Clinton and now runs a private security firm, said the agency is operating at an elevated level of alert but remains under severe time pressure to implement further changes.
"The Secret Service now has to play at a level of enhanced security that they've never dreamed of before," Miller told Fox News Digital. "But here's the bad news for the Secret Service: They don't have time. This threat is now."
Bill Gage, a former Secret Service special agent who served under Presidents George W. Bush and Barack Obama, said the agency typically conducts reviews after violent incidents even when it did not provide on-site protection. He said the review of Kirk’s assassination will likely prompt renewed attention to smaller protection details, such as those assigned to family members, which sometimes include only a few agents.
"I think they will probably be taking another look at probably beefing up those smaller details that sometimes might only have two, maybe three agents on it," Gage said, adding that such adjustments would further strain agency resources.
A bipartisan House task force that investigated the Butler, Pennsylvania, attack concluded last year that the July 2024 assassination attempt was preventable and identified multiple failures that were not isolated. In response, the Secret Service has taken steps to modernize aspects of its operations, including expanding the use of drones for surveillance, increasing counter-drone technology, and overhauling radio communications and interoperability with state and local law enforcement, former acting Secret Service director Ronald Rowe told lawmakers in December 2024.
Despite those reforms, experts warned the agency remains stretched. Miller said the Secret Service should train to more aggressive standards and that the recent killings and attempts are not isolated incidents. A government watchdog has also raised concerns about critical personnel shortfalls, including a reported sniper shortage, that could leave senior officials and protectees more vulnerable.
The Secret Service extended condolences to the Kirk family but declined to discuss specific operational changes or tactics. "President Trump receives the highest levels of U.S. Secret Service protection and the agency adjusts our protective posture as needed to mitigate evolving threats," a spokesperson said in a written statement. "Out of concern for operational security, we cannot discuss the means and methods used for our protective operations."
Investigations into the 2024 attempts on Trump are ongoing. The alleged shooter in Butler, Pennsylvania, was identified as Thomas Matthew Crooks, who authorities say fired from a rooftop during a July 2024 rally, killing a 50-year-old attendee and wounding others. The September 2024 arrest in West Palm Beach resulted in charges including attempted assassination of a major presidential candidate; that case proceeded to trial this week.
Security officials and former agents said the pattern of violence has forced the Secret Service to weigh tactical adaptations against persistent resource constraints. They said the agency’s changes since last year—expanded technical surveillance, improved communications, and greater coordination with other law enforcement—represent significant steps but may be insufficient if threats continue to accelerate.
With multiple investigations and prosecutions underway, and with public events continuing to draw sizable crowds, former agents said the agency faces difficult choices about where to allocate limited personnel and technology. They said any reallocation toward higher-risk, smaller details or family protection will likely exacerbate broader manpower challenges.
The episode underscores the evolving nature of political violence in the United States and the operational pressures on the federal agency responsible for protecting the president and other designated individuals. Lawmakers, watchdogs and security experts said the agency’s ability to adapt quickly while maintaining routine protection duties will be closely watched in the weeks ahead.
