His tweet got over one million likes and 114,000 retweets.

Musk's mother, Maye Musk, reprimanded with "That's not funny."

A Twitter user replied to his tweet saying, “Your Tweet just inoculated you against the very thing you're concerned about. 90+ million people have got your back.”

Another user said, “The world needs Elon Musk.”

The American YouTuber Mr Beast also replied to Musk's tweet, asking "If that happens can I have Twitter," to which Musk replied with, "Ok."

Musk’s tweet came minutes after he shared a post which appears to be a communication from a Russian officer that indicates Musk is involved in "supplying the fascist forces in Ukraine with military communication equipment. And for this, Elon, you will be held accountable like an adult - no matter how much you'll play the fool.”
