Donald Trump walks out of TV interview on wiretapping

US President Donald Trump has been deliberately vague on claims that former President Barack Obama wiretapped him before storming out of a television interview with CBS News.

Mr Trump fired serious allegations at his predecessor in March, taking to Twitter to claim that Mr Obama had fitted Trump Tower with wiretaps designed to derail his presidential campaign.

FBI director James Comey told a congressional hearing there was no evidence to suggest Mr Trump's claims were correct, and the President copped plenty of heat for making the allegations without evidence.

Now, in a televised interview with CBS political reporter John Dickerson, he half-heartedly defended his claims and said it's up to people to form their own opinions, before cutting the interview short.

The awkwardness started when Dickerson asked what President Trump and Mr Obama's relationship was like.

"He was very nice to me but after that, we've had some difficulties - so it doesn't matter," he said.

"You know, words are less important to me than deeds. And you saw what happened with surveillance."

When asked what the difficulties were, Mr Trump again raised the issue of ex-President Obama's alleged wiretapping - but when pushed to speak definitively on the topic, he refused.

"You can figure that out yourself. He was very nice with words and when I was with him but, after that, there has been no relationship," he said.

"Do you stand by that [wiretapping] claim?" Dickerson asked.

"I don't stand by anything," President Trump replied. "You can take it the way you want. I think our side's been proven very strongly and everybody's talking about it, and frankly it should be discussed.

"I think that is a very big surveillance of our citizens. It is a very big topic, and it's a topic that should be number one, and we should find out what the hell has been going on."

When Dickerson continued to push Mr Trump, asking him to clarify why he'd called Mr Obama "sick" and "bad" for his alleged surveillance, he continued to deflect before walking away.

"You don't have to ask me. I have my opinions and you can have your own opinions," Mr Trump said.

"But I want to know your opinions, because you're the President of the United States," Dickerson pushed.

"Alright, that's enough. Thank you. Thank you very much," Trump replied, before returning to his desk in the Oval Office as Dickerson smiled wryly to himself.

The walk-out comes as President Trump revealed that he'd meet with North Korean leader Kim Jong-Un "under the right circumstances".
