Kash Patel has called for radical changes at the FBI and was a fierce and vocal critic of the bureau's work as it investigated ties between Russia and Donald Trump's 2016 presidential campaign.
Now the steadfast Trump ally has been tapped to lead the federal law enforcement agency he's pushed to overhaul.
A look at Patel, Trump's pick to replace Christopher Wray atop the FBI.
Side-by-side with Trump
Patel has for years been a loyal ally to Trump, finding common cause over their shared skepticism of government surveillance and the ''deep state'' — a pejorative catchall used by Trump to refer to government bureaucracy.
He was part of a small group of supporters during Trump's recent criminal trial in New York who accompanied him to the courthouse, where he told reporters that Trump was the victim of an ''unconstitutional circus.''
That close bond would depart from the modern-day precedent of FBI directors looking to keep presidents at arm's length.
Former FBI Director James Comey, who was fired by Trump in May 2017, memorably recoiled when Trump asked him during a private dinner to pledge his loyalty to him. And Wray, who had no personal connection to Trump when he was picked to replace Comey, broke with Trump on different hot-button issues and served as FBI director during investigations into Trump that ultimately led to his indictment.
