CNN Exclusive: Russian officials requested adding convicted murderer to Griner/Whelan prisoner swap

Russian government officials requested that a former colonel from the country's domestic spy agency who was convicted of murder in Germany last year be added to the US' proposed swap of a notorious arms dealer for Brittney Griner and Paul Whelan, multiple sources familiar with the discussions told CNN.

The Russians communicated the request to the US earlier this month through an informal backchannel used by the spy agency, known as the FSB, that they wanted Vadim Krasikov released in addition to Viktor Bout, the sources said. Krasikov was convicted in December of murdering a former Chechen fighter, Zelimkhan "Tornike" Khangoshvili, in Berlin's Kleiner Tiergarten in 2019 and sentenced to life in prison.

The request was seen as problematic for several reasons, the sources told CNN, among them that Krasikov remains in German custody. As such, and because the request was not communicated formally but rather through the FSB backchannel, the US government did not view it as a legitimate counter to the US' offer which was first revealed by CNN on Wednesday.
