Alexander Vindman is a retired United States Army Lieutenant Colonel who was the Director for European Affairs for the United States National Security Council (NSC). In October 2019, he gained national attention after testifying before the US Congress regarding the Trump–Ukraine scandal, providing evidence that resulted in a charge of abuse of power in the impeachment of Donald Trump. He was subsequently reassigned within the army on February 7, 2020, and amidst claims of retaliation, he retired from military in July that year blaming vengeful behavior and bullying by President Trump and administration officials. He previously served as an infantry officer in the Iraq War and had overseas assignments to South Korea and Germany before serving as a foreign area officer specializing in Eurasia in the U.S. embassies of Russia and Ukraine.
