FBI Director Kash Patel is making bureau staff take polygraph tests to root out anyone who’s been talking trash about him, according to a report. Patel has ramped up the FBI’s use of the lie-detector tests—often deemed too unreliable to use as evidence in criminal courts—in order to keep tabs on his own people and stamp out leaks.

The FBI is searching for a protester who appeared to open fire at federal agents during an immigration operation at a cannabis farm in Camarillo on Thursday.
