The repost, later deleted by Musk, said: "Stalin, Mao, and Hitler didn’t murder millions of people. Their public sector employees did.”

Musk and Tesla have faced heightened criticism since the billionaire made a gesture likened to a Nazi salute during an inaugural event in January.

This is all normal enough, but his latest retweet has outraged people on Twitter as he shared a post that attempted to downplay the role Adolf Hitler, Joseph Stalin, and Mao Zedong had on the deaths of millions. The retweeted post read: “Stalin, Mao, and Hitler didn’t murder millions of people. Their public sector workers did.”
