Tense Trump interview covers Kavanaugh to Kim Jong Un

US President Donald Trump has been grilled in an interview with 60 minutes, and claimed his relationship with Kim Jong Un prevented nuclear war.

Shown a video of himself saying he was "in love" with the North Korean Dictator, Trump seemed proud of his relationship with the notoriously hostile leader.

"We were going to war with North Korea," said Trump, claiming Obama had led America to the verge of war with the nuclear power.

"Now you don't hear that, you don't hear any talk of it, and he doesn't want to go to war."

Journalist Lesley Stahl read the US President a list of some of Kim Jong Un's most controversial rulings as dictator.

Trump snapped at Stahl, saying, "I'm not a baby, I know all these things."

He said there was "good chemistry" between the two, but North Korea is still yet to give up any of its weapons, and Trump admitted he didn't know whether they were making more.

Later, Stahl asked what Trump thought of the immigration law separating children from their parents at the US border.

The US president defended the law, claiming it was the same under the Obama administration.

"There have to be consequences," he said, "when you allow the parents to stay together, then what happens is you're gonna have people pouring into the country."  

Stahl queried Trump's defence of recently confirmed Supreme Court Judge Kavanaugh, through allegations of sexual abuse.

"It doesn't matter, because we won," said the US president to claims he was unfair to Kavanaugh's alleger, Dr Christine Blasey Ford.

Asked whether he still believed climate change was a hoax, Trump said, "I think something is happening, something's changing, but I don't know if it's man-made."

"I'm not denying climate change but it could very well go back."

Ending on what he's learnt over his two years in the White House, Trump said politics was "the most deceptive, vicious world."

"Washington DC is a vicious, vicious place, the attacks, the bad-mounting, the speaking behind people's backs. In my way I feel very comfortable here."
