we've got to get an FBI that is back focused on protecting the homeland and preventing, whether it be terrorists or espionage taking place.
Seek to restore the FBI's focus on counterterrorism and counterespionage instead of diverting agents to immigration enforcement.
Occurrences
Evidence
In a Senate floor speech, Sen. Mark R. Warner highlighted that the Trump administration had reassigned between 25% and 45% of FBI agents from counterterrorism, cyber, espionage, and child exploitation cases to immigration enforcement, reducing the Bureau's ability to prevent attacks and respond to cyber intrusions.
According to data obtained by Sen. Mark R. Warner, nearly a quarter of the FBI's approximately 13,000 agents were reassigned to immigration enforcement, reflecting a significant shift in the agency's focus.
Sources indicated that the FBI planned to reallocate thousands of agents from immigration enforcement back to counterterrorism efforts, prompted by U.S. strikes in Iran.
Sen. Warner welcomed an audit by the DHS Inspector General to evaluate processes preventing the arrest of U.S. citizens during immigration enforcement operations, highlighting concerns over aggressive enforcement actions.
Senators Warner and Kaine urged the DHS Inspector General to investigate DHS's collection and use of sensitive personal data, expressing concerns over potential civil liberties violations.
Sen. Warner detailed how thousands of FBI agents and senior leaders were forced out for political reasons, including heads of counterterrorism, intelligence, cyber, and critical incident response units.
Warner warned that the administration's political interference, including the gutting of the FBI's operational capabilities and the erosion of federal cyber defenses, is leaving Americans at growing risk.
Warner highlighted that the administration's actions, including reassigning FBI agents to immigration enforcement, have sharply reduced the Bureau's ability to prevent attacks, disrupt foreign plots, and respond to cyber intrusions.
The report says FBI agents stopped Lorenzo Rojas-Martinez in Atlanta over a restricted-airspace drone violation and then turned him over to ICE custody on an illegal-re-entry case.
AP reported that law enforcement disrupted a planned attack on the White House UFC event and that the FBI made arrests in multiple states after reviewing encrypted messages and operational plans.
Federal prosecutors charged 15 people tied to Operation Metro Surge, describing a continuing immigration crackdown that had produced more than 4,000 arrests and frequent clashes with federal agents.
The White House's May 2026 counterterrorism strategy prioritizes cartels, legacy Islamist terrorists, and violent left-wing extremists, and says the government will use law-enforcement, intelligence, military, and cyber tools against them.
Assessments
As a U.S. senator, Warner had oversight and advocacy tools but not direct control over FBI deployment. The record shows a serious effort: he publicly documented the diversion of FBI agents to immigration enforcement, used Senate-floor speeches and oversight pressure, and backed investigations related to aggressive immigration-enforcement practices. But the evidence does not show that he secured a binding policy change that restored the FBI's focus to counterterrorism and counterespionage. Reported shifts of agents back toward counterterrorism appear tied to executive-branch decisions and external security events, not a Warner-driven delivered outcome, and immigration-focused federal enforcement remained active into 2026. Under the federal office context, that supports failed delivery with meaningful effort rather than full or partial completion.
Sen. Warner repeatedly raised alarms and took oversight actions aimed at restoring the FBI's focus on counterterrorism and counterespionage: he publicized data on large-scale reassignments of agents (evidence 2450/2451), delivered Senate floor speeches criticizing the shifts and political purges (2450/2453/2455/2456/2457), and urged and welcomed DHS IG audits and investigations into related enforcement practices (2454/2453). Those activities represent sustained, tangible pressure and oversight efforts during his term. However, available evidence does not show a clear, attributable, full restoration of the FBI's counterterrorism/counterespionage staffing to pre-reassignment levels; at best there are reports the FBI planned some reallocation back to national-security duties (2452), but causation and completeness are unclear. Therefore the promise is partially fulfilled: significant effort and some movement, but not demonstrable complete delivery.
Evidence shows Senator Warner consistently raised concerns about the diversion of FBI resources from counterterrorism and counterespionage to immigration enforcement, took public stands, urged oversight, and highlighted the negative effects. There is indication of planned shifts to return FBI focus, but not conclusive evidence that the promised objective—restoring the FBI's primary focus—was fully achieved. Warner demonstrated effort through oversight calls, Senate speeches, and pressing for audits, justifying an effort badge and a partial rating.
