President Trump refused to “pledge” that he would not shut down special counsel Robert Mueller’s Russia probe, doubling down on his claims that he didn’t engage in any collusion with the Kremlin.

“I don’t pledge anything. But I will tell you, I have no intention of doing that. I think it’s a very unfair investigation because there was no collusion of any kind,” Trump told CBS’ “60 Minutes” in an interview that aired Sunday.

Pressed by the news show’s correspondent Lesley Stahl, Trump was adamant there was no collusion.

“I don’t want to pledge. Why should I pledge to you? If I pledge, I’ll pledge. I don’t have to pledge to you. But I have no intention of doing that,” he said.

Trump dismissed any connection to Moscow even though 32 people have been charged or pleaded guilty in Mueller’s investigation, including his former campaign chairman Paul Manafort, his former National Security Adviser Michael Flynn and his longtime personal attorney Michael Cohen.

“Do you really think I’d call Russia to help me with an election? Give me a break. They wouldn’t be able to help me at all. Call Russia. It’s so ridiculous,” he told CBS.

Asked about Russian meddling in the 2016 election, Trump said China was interfering as well.

“They — they meddled. But I think China meddled too,” he said.

“You are diverting the whole Russia thing,” Stahl asked.

“I’m saying Russia, but I’m also saying China,” Trump said.

The president also said he was tough on Russian President Vladimir Putin and brought up the Helsinki summit in July when he sided with Putin over the consensus of the US intelligence community that Moscow interfered in the election.

“I think I’m very tough with him personally. I had a meeting with him. The two of us. It was a very tough meeting and it was a very good meeting,” Trump said.

Asked about Putin’s involvement in assassinating political foes, Trump said, “Probably he is, yeah.”

“But I rely on them, it’s not in our country,” he added.

Trump was also asked about comments he made last month that he and North Korean leader Kim Jong-un exchanged letters and “then we fell in love” even though the despot has a history of starving his people, executing them in public or locking them up in gulags.

“Sure. I know all these things. I mean — I’m not a baby. I know these things,” he said.

“But you love him?” Stahl asked.

“That’s just a figure of speech,” Trump replied.

But “he’s a bad guy,” she pressed.

“Look. Let it be whatever it is. I get along with him really well. I have a good energy with him. I have a good chemistry with him,” Trump said. ” Look at the horrible threats that were made. No more threats. No more threats.”

In a lighter moment, Trump said that at the onset of his administration it was “surreal” to refer to himself as the president but over time he’s become more comfortable with the title after he “learned on the job.”

“I mean, I felt comfortable at the beginning, other than it was a little surreal to say I’m the president of the United States, but I think that’s true with everybody,” he said.

Trump said that reticence has faded away over the first 20 months of his administration.

“Now I very much feel like POTUS. I do. I feel like the president. You know, for a little while, it’s like ‘Mr. President, sir.’ It’s — even my friends, they call me, they — they don’t call me Donald — they call me Mr. President. And I say, ‘Will you please loosen up?’ I’ve learned on the job. I have,” he said.
