The FBI has cut staffing in its domestic terrorism office and eliminated a tool used to track such investigations, raising concerns about the agency's ability to counter extremist threats. The changes, which come under FBI Director Kash Patel, a critic of the effort, could hinder the monitoring of white supremacists and anti-government extremists and disrupt law enforcement's ability to disrupt plots. Despite warnings from U.S. officials about the significant security threats posed by domestic violent extremists, the Trump administration has directed the FBI's Joint Terrorism Task Forces to assist in the immigration crackdown. The changes also follow Trump's pardon of individuals charged in the Jan. 6 attack on the Capitol.
