US secretary of state Antony Blinken said on Wednesday the US has offered to release Victor Bout, a convicted Russian arms trafficker serving a 25-year prison sentence, in exchange for WNBA star Brittney Griner and former US marine Paul Whelan, CNN and Axios report.

Griner testified at her trial in Russia on Wednesday, saying that a language interpreter only translated part of what she said during her questioning, according to The Associated Press. Griner has been detained since February and faces up to 10 years in prison after Russian officials said they found cannabis oil in her luggage.
