Senate Judiciary Democrats said Pam Bondi and Kash Patel redirected more than 9,000 FBI personnel to immigration enforcement under Donald Trump, a shift they argue is transforming the Federal Bureau of Investigation into a central instrument of the administration's deportation agenda.

The claim, outlined Monday by Democrats on the Senate Judiciary Committee, aligns with reporting from The Intercept that 9,161 FBI employees-nearly a quarter of the bureau's roughly 38,000 staff-were assigned to immigration-related work during the first nine months of Trump's current term. That represents a dramatic increase from just 279 agents focused on immigration cases before January 2025.

The reallocation reflects a broader recalibration of federal law enforcement priorities. Under Patel's leadership, the FBI has elevated illegal immigration, violent crime and drug trafficking as core mission areas, a move administration officials describe as a return to foundational public safety objectives.

Patel has defended the approach in congressional testimony, stating that FBI-led task forces include more than 9,000 partners across federal, state and local agencies. He also cited enforcement outcomes, noting more than 25,000 immigration-related arrests since Jan. 20, 2025, alongside operations targeting groups such as Tren de Aragua and MS-13.

Democrats, however, contend that the numbers underscore a diversion of specialized resources. They argue that assigning FBI agents-traditionally focused on counterterrorism, cybercrime and public corruption-to immigration enforcement risks weakening the bureau's core national security functions.

Chris O'Leary, a former FBI senior executive, told The Washington Post: "We are weakening ourselves day by day," adding that using FBI agents for immigration arrests was "a misuse of exquisite ability."

Data cited by The Washington Post suggests the shift has been uneven across the country. While nearly a quarter of the FBI's 13,000 agents have been reassigned nationwide, the proportion has exceeded 40% in some large field offices, according to figures obtained by Sen. Mark Warner.

The administration maintains that immigration enforcement is now central to national security strategy. A White House spokesperson, Abigail Jackson, told the Los Angeles Times: "President Trump's highest priority has always been the deportation of illegal alien criminals who endanger American communities."

The policy shift is occurring alongside a significant expansion of federal immigration operations:

  •  ICE aims to remove 1 million people over the current and next fiscal year
  •  Deportations last year totaled approximately 442,000
  •  Congress has allocated more than $170 billion for immigration enforcement
  •  Detention capacity is being expanded to approximately 100,000 individuals

Traditionally, immigration enforcement has been led by agencies such as Immigration and Customs Enforcement, with the FBI supporting cases tied to criminal investigations. The current approach blurs those institutional boundaries, embedding FBI resources directly into large-scale immigration operations.

Supporters of the policy argue the integration enhances coordination against transnational criminal networks and cartel activity. Critics counter that the scale of the reassignment reflects a structural transformation of the bureau's mission, prioritizing immigration enforcement at the expense of intelligence-driven investigations.
