Billionaire Elon Musk was ripped in a post online by Anti-Defamation League (ADL) CEO Jonathan Greenblatt for "offensive" and "inappropriate" remarks about Nazis.

After the Israeli prime minister defended Musk following controversy over a gesture at a Trump rally, the tech entrepreneur posted puns using the names of notorious Nazi officials.

And, Elon Musk’s controversial arm gesture continues to divide opinions as to its meaning. Some have insisted it was a Nazi salute, while Musk has said the comparisons to Hitler were “tired” and “dirty tricks”.
