Musk said on Monday that he was challenging Putin to single combat over Russia's invasion of Ukraine.
Musk challenged Putin to single combat. The stakes are Ukraine.
He shared a translated English version of some of those words.
He tagged the Russian presidency's official account on the social media site and asked if they agreed to the fight.
He didn't give any more information about how this would happen.
Russia invaded Ukraine on February 24. The representatives of the two countries are due to meet again on Monday.
After the invasion, Musk sent Starlink systems to Ukraine.
The company took a jab at Russia.
The head of the Russian space agency said earlier this month that Russia would no longer send rocket engines to the US in response to sanctions. I don't know what.
As the company launched Starlink satellites on Wednesday, the launch director responded: "Time to let the American broomstick fly and hear the sounds of freedom."
