Stephen Hubbard, the only US citizen designated by Washington as wrongfully detained in Russia, was at St Petersburg's Pulkovo Airport on October 21 and was set to fly back to the United States with envoy Steve Witkoff, according to Putin. He had been sentenced in October 2024 to six years and 10 months in prison after a Moscow court found him guilty of serving as a mercenary for Ukraine's territorial defence forces in the Kharkiv region. Russian prosecutors said he fought under a contract worth $1,000 per month.
Hubbard's sister, Patricia Fox, has expressed doubts about the accusations, saying her brother had been sympathetic to Russia, moved to Ukraine in 2014, and was living in the city of Izyum when the war began. She pointed to a video from May 2022 in which Hubbard claimed to have seen Ukrainian forces shelling Izyum and voiced understanding for Putin's decision to invade. It remains unclear whether he was coerced.
Trump wrote on Truth Social, "Welcome home, Stephen. It's great to have you back." He said the release was unprecedented because the US gave nothing in return. However, after the latest call between Trump and Putin, the US president announced a deal to encourage Russian diesel exports and waived sanctions due under a law he had signed the previous month. Kyiv and Western allies have warned that such measures could fuel Moscow's war effort.
At least five other Americans are believed to remain in Russian detention. The case has become a prominent political issue ahead of November's US midterm elections, as efforts to end the full-scale invasion of Ukraine continue without a breakthrough.
