Brittney Griner: We never stopped pushing for her release - Biden

The US and Russia have exchanged jailed US basketball star Brittney Griner for notorious arms dealer Viktor Bout, held in an American prison for 12 years.

Griner was arrested at a Moscow airport in February for possessing cannabis oil and last month sent to a penal colony.

President Biden said: "This is a day we worked toward for a long time. We never stopped pushing for her release."
