WASHINGTON — President Trump hit back at former CIA Director John Brennan, who had called the president’s performance at Monday’s press conference with Russian President Vladimir Putin “nothing short of treasonous.”

“Well, I think Brennan is a very bad guy and if you look at it, a lot of things happened under his watch,” Trump said in a pre-taped interview with Fox News Channel’s Tucker Carlson, which aired Tuesday night. “I think he is a bad person.”

Brennan left his top post at the spy agency as Trump was coming into office, criticizing the incoming president on his way out. He’s been a thorn in Trump’s side ever since.

Carlson defended Trump’s performance at the Helsinki summit in his opening monologue and blamed the president’s bad reviews on neo-conservatives from the Bush years still in media and government who believe Russia should always be branded a threat.

Trump had his own set of people to blame, not only bashing Brennan, but bringing up FBI lovers Peter Strzok and Lisa Page, along with former FBI Deputy Director Andrew McCabe — who was fired in May, a day before his retirement — and ex-FBI Director James Comey, who was fired by Trump the year before.

“These are people that, in my opinion, are truly the bad people and they are being exposed for what they are and it’s a shame that it has to happen, but it’s really hurt our country,” Trump said.

When discussing Russia, however, the president was hesitant to label it an adversary.

“I don’t even want to use the word ‘adversary,’” he said. “We can all work together. We can do great. Everybody can do well and we can live in peace.”

In contrast, in an interview with CBS Sunday, Trump raised eyebrows when he called the European Union, a longtime ally of the United States, a “foe.”

Carlson’s interview with Trump was pre-taped Monday and since then, the president has walked back some of the comments he made while in Helsinki, including the impression that he left that he believed Putin’s denial of election meddling over the assessment of his own intelligence community.

However, he has continued to call the summit with the Russian leader a success.

“The meeting between President Putin and myself was a great success, except in the Fake News Media!” Trump tweeted Tuesday night.

Trump also hasn’t wavered on the subject of immigration.

On Friday, he told European leaders that immigration was “changing the culture” of their countries. “I think it’s a very negative thing for Europe. I think it’s very negative. And I know it’s politically not necessarily correct to say that, but I’ll say it and I’ll say it loud.”

Despite getting pushback for the comments he made, he repeated that sentiment when he sat down with Carlson.

The Fox News pundit asked him if he could “think of a place that has been improved by mass immigration or movements of large numbers of refugees?”

“Not one,” Trump replied.
