In a significant development on April 10, 2025, U.S. Secretary of State Marco Rubio announced the release of Ksenia Karelina, a dual U.S.-Russian citizen, who was held in Russian custody for over a year. Karelina had faced a severe 12-year prison sentence for purportedly committing treason by donating a nominal sum of $50 to a nonprofit assisting Ukraine.

Rubio revealed that Karelina is now en route back to the United States, emphasizing her wrongful detention. The prisoner exchange took place in Abu Dhabi, in coordination with ongoing U.S.-Russian diplomatic talks aimed at restoring flight services and embassy staff levels.

This release follows another significant swap earlier this year when American teacher Marc Fogel was freed from a Russian prison on drug charges, a deal that saw the U.S. release Russian Alexander Vinnik, convicted of money laundering. These recent events suggest a possible shift in the historically tense U.S.-Russia relations, indicating a willingness to negotiate and resolve issues through diplomacy.
