The U.S. and Russia agreed to a prisoner swap involving Marc Fogel, an American schoolteacher who the Biden administration had deemed wrongfully detained by Russia, in a diplomatic move that the White House said could move forward negotiations to end the war in Ukraine.

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.
