President Trump, in an all-out feud with the country’s intelligence community over persistent leaks, will begin a major review of the spy agencies, according to a report.

Trump is set to tap a billionaire financier, Stephen Feinberg, to lead the review, which has been met by “fierce resistance” by the intelligence agencies, The New York Times reported.

The selection of Feinberg, co-founder of hedge fund Cerberus Capital Management and a member of the president’s economic advisory council, signals the president’s attempt to keep the review process within the White House. Details of the review – its scope and timeline – have not yet been determined.

The findings of any White House review would give Trump ammo should he seek full-scale change to the way intelligence agencies operate.

Trump this week blasted the nation’s intelligence community over leaked phone conversations former National Security Adviser Michael Flynn had with a Russian ambassador over US sanctions.

“From intelligence, papers are being leaked, things are being leaked; it’s criminal action. It’s a criminal act, and it’s been going on for a long time before me, but now it’s really going on,” Trump said during his joint news conference with Israeli Prime Minister Benjamin Netanyahu on Wednesday.

He also called the intelligence leaks “Very un-American!” in a Wednesday tweet.

On Tuesday, White House press secretary Sean Spicer said Flynn was forced out over an “eroding level of trust” after he “misled the vice president and others” regarding his pre-inauguration phone conversations with Russian Ambassador Sergey Kislyak.

During the transition period, Trump compared intel agencies to Nazis.

“Intelligence agencies should never have allowed this fake news to ‘leak’ into the public. One last shot at me.Are we living in Nazi Germany?” he said on Twitter.
