Kash Patel, who is President Donald Trump’s nominee for FBI director, was accused of directing firings of senior FBI officials from outside the agency.

A top Democratic senator has asked the Justice Department’s inspector general to investigate after he says he received information that Kash Patel had been “personally directing the ongoing purge” of agents at the bureau.

Patel is a controversial nominee, having long raged against the so-called Deep State and prioritized his loyalty to Trump.
