The head of the FBI's New York field office resigned Monday afternoon, facing pressure from President Donald Trump's administration. James Dennehy announced his resignation in an email to staff, NBC News reported. His resignation comes after Kash Patel began his first week leading the bureau last week. Before that, Justice Department deputy attorney general, Emil Bove, began a search for all FBI staff who worked on cases around the Jan. 6 attackers. Dennehy clashed with Bove over that probe into the staff.
