Marc Fogel, an American history teacher who was deemed wrongfully detained by Russia, has been released and returned to the U.S. in what the White House described as a diplomatic thaw that could advance negotiations to end the war in Ukraine. Steve Witkoff, a special envoy for President Donald Trump, left Russia with Fogel and brought him to the White House, where Trump greeted him. “I feel like the luckiest man on Earth right now,” Fogel said as he stood next to Trump with an American flag draped around his shoulders. Fogel, who is from Pennsylvania and was expected to be reunited with his family by the end of the day, said he would forever be indebted to Trump. Trump said another American would be released on Wednesday, though he declined to name the person or say from what country, only saying it was someone “very special.” The president declined to say if he spoke to Russian President Vladimir Putin about Fogel, but Fogel praised the Russian leader as “very generous and statesmanlike in granting me a pardon.” Asked about the terms of the deal, Trump said: “Very fair, very, very fair, very reasonable. Not like deals you’ve seen over the years. They were very fair.” He did not say what the United States exchanged for Fogel’s release. Fogel was arrested in August 2021 and was serving a 14-year prison sentence. His family and supporters said he had been traveling with medically prescribed marijuana, and he was designated by President Joe Biden’s administration as wrongfully detained in December. Michael Waltz, Trump's national security adviser, said the U.S. and Russia “negotiated an exchange” to ensure Fogel's release. He did not say what the U.S. side of the bargain entailed. Previous negotiations have occasionally involved reciprocal releases of Russians by the U.S. or its allies. Waltz said the development was “a sign we are moving in the right direction to end the brutal and terrible war in Ukraine.” Trump, a Republican, has promised to find a way to end the conflict. Trump also has talked about having a good relationship with Putin, who launched a full-scale invasion of Ukraine in 2022. Last month, Trump said his administration was having “very serious” conversations with Russia about the war. On Tuesday, Trump said Fogel's release "could be a big important part of getting the war over with Ukraine." There was no immediate comment from Moscow about Fogel’s release on Tuesda
