In a wide-ranging interview, host Carol Castiel and senior managing editor in VOA’s Ukrainian Service, Tatiana Vorozhko, speak with Lt. Col. Alexander Vindman about the significance of his congressional testimony in 2019 regarding the infamous telephone call between former President Donald Trump and newly elected Ukrainian President, Volodymyr Zelenskyy, which led to Trump’s first impeachment. Vindman also tells VOA that Ukrainian President Zelenskyy’s strength of character, along with Ukrainians’ resilience and battlefield skill, have enabled the country to thwart Russian offensives and why Washington’s robust military and humanitarian support is critical not only for Ukraine’s success but also for the preservation of the democratic liberal world order.
