Elon Musk was punched in the face by his 5-year-old son, X, while they were playfully horsing around, which caused Musk's black eye visible during a recent press conference at the White House.

There was also a separate incident where Elon Musk physically fought with Treasury Secretary Scott Bessent. Musk hit Bessent's ribcage like a rugby player after Bessent called him a fraud, and Bessent hit Musk back before others intervened to break up the fight. However, this fight was not the cause of Musk's black eye.

In summary:

• The black eye Musk showed off publicly was from his son punching him playfully.

• Musk had a distinct physical confrontation with Scott Bessent involving blows but that did not cause the black eye.
