Elon Musk has accused President Biden of causing something "far worse than 9/11."

The CEO of X, formerly Twitter, accused Biden of "treason" over allegations of "importing voters" ahead of this year's presidential election.

Musk has been an outspoken critic of President Biden's immigration policy.

It comes after a secret Biden program was exposed where the administration admitted to flying 320,000 migrants into the US, but officials refuse to say who was flown and to where.

Taking to social media, Musk wrote: "Treason indeed! Ushering in vast numbers of illegals is why Secretary Mayorkas was impeached by the House.

"They are importing voters. This is why groups on the far left fight so hard to stop voter ID requirements, under the absurd guise of protecting the right to vote."

He later added: "This administration is both importing voters and creating a national security threat from unvetted illegal immigrants.

"It is highly probable that the groundwork is being laid for something far worse than 9/11. Just a matter of time.

Musk continued: "Three things America needs: - Secure borders - Safe cities - Sensible spending."

He also reposted a post from right wing commentator Mario Nawfal, who claimed that "US has five million more illegal migrants than it did in 2020:

"A diagram showing the exponential increase in illegal migration since Biden took office. The total number of illegal migrants in the country has almost tripled in that time."

He responded saying: "Wow"
