The former head of the United States Central Intelligence Agency and a staunch supporter of President Donald Trump is facing a political backlash after he suggested Russia was behind the assassination of Russian President Vladimir Putin.
Russian officials have called for a complete shutdown of the US intelligence community.
In an interview with The Washington Post, Elon Musk said he believes the assassination was staged and a “corrupt attempt to manipulate events” to “make it appear that Russia was interfering in our election”.
“It’s a total fraud.
It’s a massive fraud,” Mr Musk said.
Mr Musk said Russia’s actions were an attempt to “disrupt” the US election process.
“I believe that Putin is trying to destabilise the United Sates politics and our democracy.
And I think that that is a pretty good conclusion,” he said.
He also said he was not in favour of the Russian-US economic sanctions regime.
“Russia has a good relationship with the US, so it doesn’t make sense to take a step that would hurt them,” he told the Post.
“If you want to get the sanctions out, then you need to stop the Russia sanctions, and we have a very good relationship.”
Mr Musk also said the US was “not going to let Russia invade us”, adding that if Moscow had “suddenly” invaded a US city, it would “probably be a different story”.
The US has repeatedly accused Russia of attempting to interfere in the 2016 US presidential election.
Mr Musk, who is a billionaire investor, was also a vocal critic of President Trump’s decision to withdraw from the Paris climate agreement.
“The Paris Agreement is a disgrace,” he tweeted.
“We must fight climate change and the fossil fuel industry to the death, before we can even consider any new agreements.”
He has said he does not support the Iran nuclear deal.
