Tesla CEO and 'X' boss Elon Musk has accused the Joe Biden administration in the US of "importing voters" and "creating a national security threat". Musk added that it is "highly probable that the groundwork is being laid for something far worse than 9/11" - a reference to the September 2001 terror attacks by Al-Qaeda that left nearly 3,000 people dead. In the accompanying post, Musk wrote, "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."
