Julie Davis, the acting US ambassador to Ukraine, is set to resign after serving for less than a year, as reported by the State Department. Sources indicated that she has been frustrated with President Donald Trump's lack of support for Ukraine amid the ongoing Russian invasion. Despite these claims, the State Department spokesperson Tommy Pigott asserted that her resignation is due to retirement, not any differences with the President. Davis, who has also been serving as the US ambassador to Cyprus since 2023, was appointed by the Trump administration in May 2022. Her predecessor, Bridget Brink, expressed concerns over Trump's perceived appeasement of Russia and pressure on Ukraine. Since taking office in January 2025, Trump has been criticized for assigning blame to Ukraine for the invasion and has had a strained relationship with Ukrainian President Volodymyr Zelenskyy. The ongoing conflict has seen US-brokered ceasefire efforts stall, as Washington's focus has shifted towards other international conflicts.
