Alexander Vinnik, a convicted Russian criminal, is being freed as part of a swap that saw Moscow’s release of American Marc Fogel, two U.S. officials confirmed Wednesday. Vinnik was arrested in 2017 in Greece at the request of the U.

Fogel was sentenced to 14 years in prison in Russia, which the U.S. has condemned as a wrongful detention, after a small amount of medical cannabis was found in his luggage.
