FBI Director Kash Patel is facing intense questioning from U.S. senators as lawmakers scrutinize his leadership, the bureau’s investigations and its handling of politically sensitive cases.

Patel is appearing before the Senate Judiciary Committee for an oversight hearing focused on the FBI’s operations and priorities. Republican lawmakers are expected to highlight the bureau’s work against violent crime, drug trafficking and national security threats. They are also likely to question the FBI’s handling of investigations connected to the 2020 presidential election.

Democratic senators, meanwhile, are expected to press Patel over controversial decisions made during his tenure, including the removal or reassignment of FBI officials involved in politically sensitive investigations. Questions are also likely to cover allegations of political interference, the use of government resources and Patel’s broader approach to running the bureau.

The hearing comes amid an increasingly political battle over the future direction of the FBI under President Donald Trump. Patel’s testimony could provide lawmakers with fresh answers — while potentially opening another round of confrontation between the two parties.
