Elon Musk took to Twitter on Friday morning to opine about the Brittney Griner prisoner swap that brought the WNBA star home from a Russian prison in exchange for the convicted arms dealer, Viktor Bout. 

And Musk is not alone. Whelan's brother David was also surprised he'd been left behind. “I was led to believe that things were moving in the right direction, and that the governments were negotiating and that something would happen fairly soon,” he said.

Griner, the two-time Olympic Gold Medalist who had been playing for the last seven years on a Russian basketball team, was arrested one week before Russia invaded Ukraine. She was later charged and sentenced to nine years in prison for possessing less than a gram of cannabis oil.
