FBI Director Kash Patel faced tough questions from Senate Democrats as they pressed him on his agency’s handling of major investigations, such as the assassination of political activist Charlie Kirk, and at times got into shouting matches with him.

The Trump appointee, who has been in his position since February, told the Senate Judiciary Committee at the beginning of a regularly scheduled Sept. 16 oversight hearing that he wasn’t leaving his job, and he told critics at the outset to “please, bring it on.”

Patel is a former Republican congressional aide and an outspoken supporter of President Donald Trump, who has criticized the FBI's past investigation into Trump's ties to Russia. Democrats opposed Patel's confirmation.

Republicans generally praised Patel during the hearing, and Chairman Chuck Grassley, a Republican from Iowa, read off a list of complaints with the FBI's work during from Democratic administrations.
