Marie Yovanovitch is a former U.S. Ambassador to Ukraine, serving from 2016 until 2019. She is a career diplomat with over 30 years of experience in the U.S. Foreign Service, focusing on Eastern Europe and the former Soviet Union. Yovanovitch played a key role in promoting U.S. interests and supporting Ukraine's efforts toward democracy and reform. Her tenure as ambassador became widely known during the impeachment inquiry of former President Donald Trump in 2019. Yovanovitch was recalled from her position amid allegations of a smear campaign against her, which raised concerns about the integrity of U.S. diplomatic practices.
