Basketball star Brittney Griner is back home in the US after a prisoner swap with Russia. Her release after nearly ten months in detention is being celebrated as a major win for the Biden administration, but the president is facing criticism for not securing the freedom of another American locked up in Russia, Paul Whelan. The US government is also facing questions about the man who they swapped for Griner, notorious arms dealer Viktor Bout. The Pentagon says there's still some concern that Bout could return to the illicit international arms trade. Kylie Atwood breaks down the story to Sara Sidner.
