Yevgeny Vindman

In August 2020, Vindman filed a complaint of retaliation against the White House in violation of 10 U.S.C. 1034. On May 18, 2022, the Department of Defense Inspector General issued a report substantiating that Vindman faced retaliation for his role in the impeachment and the subsequent report of misconduct by NSA O'Brien. DODOIG found, "based on a preponderance of the evidence, that [Vindman] was the subject of unfavorable personnel actions from administration officials, as defined by section 1034, title 10, United States Code (10 U.S.C. § 1034), 'Protected communications; prohibition of retaliatory personnel actions.'" Furthermore, DODIG "concluded based on a preponderance of the evidence, that these actions would not have occurred or been withheld absent the reports of misconduct." In 2022, Vindman announced his retirement from the U.S. Army after 25 years of service, stating that the retaliation from the White House had irreparably harmed his career

Vindman met with an NSC Special Assistant, at the Special Assistant's request, on January 17, 2020. During their conversation, the Special Assistant raised allegations that Mr. O'Brien and Mr. Gray had engaged in sexism, Anti-deficiency Act violations, and ethical conduct violations. On January 30, 2020, Vindman met with Mr. Ellis and Mr. Eisenberg, and conveyed to them the allegations that the NSC Special Assistant had discussed with him on January 17, 2020. In his conversation with Mr. Ellis and Mr. Eisenberg, Vindman reported that an NSC staff member told him that Mr. O'Brien and Mr. Gray had engaged in sexist conduct by making inappropriate comments about women's looks; that an NSC staff member was asked to carry out personal errands in violation of 5 CFR sec. 2635.705, "Standards of Ethical Conduct for Employees of the Executive Branch, Use of official time"; that this staff member reported that NSC "Challenge" coins were purchased with appropriated funds; and that Mr. O'Brien awarded these coins to foreigners violating the Purpose Statute and the Anti-deficiency Act. On March 6, 2020, his awareness of essentially the same allegations that the NSC Special Assistant told him in mid-January 2020 was memorialized.

On February 7, 2020, Y. Vindman told NSC colleagues he expected to leave the White House's National Security Council to return to the Department of Defense. Trump had earlier implied he might remove both Vindman brothers from their posts. Later that day, Vindman was escorted out of the White House, according to his attorney. His twin brother, Lieutenant Colonel Alex Vindman, was also escorted off the White House grounds at the same time. Both were slated for reassignment within the Army.

On February 10, 2020, then-Senate Minority Leader Chuck Schumer (D-NY) sent a letter in an apparent response to the firing of the two brothers that requested federal Inspectors General investigate possible retaliation against "anyone who has made, or in the future makes, protected disclosures of presidential misconduct." On February 13, Trump's former chief of staff, retired Marine General John Kelly, defended Vindman's actions and testimony. "He did exactly what we teach them to do from cradle to grave. He went and told his boss what he just heard," Kelly said.

During a panel discussion held on February 11, 2020, at the Atlantic Council, the president's National Security Advisor, Robert C. O'Brien said that it was his decision to transfer both Vindman brothers back to the Army for re-assignment and denied that the move was ordered by Trump in retaliation for Vindman's testimony. "I can absolutely tell you that they were not retaliated against", O'Brien told the panel. O'Brien also disputed the move as being characterized as "fired" since both brothers remain on active duty. O'Brien noted that their transfer was part of a larger NSA staff reduction. His remarks contradicted Trump, who tweeted that he had ousted Vindman for insubordination and for doing "a lot of bad things."

Vindman came to national attention in October 2019 when his twin brother, Lieutenant Colonel Alexander Vindman, testified before the United States Congress regarding the Trump–Ukraine scandal. Yevgeny received the report of President Trump's phone call from Alex and reported the call to senior White House Lawyers. Alex's testimony provided evidence that resulted in a charge of abuse of power in the impeachment of Donald Trump.

In July 2018, Vindman accepted an assignment with the National Security Council. In his role on the NSC, Vindman became a deputy legal advisor. He was later promoted to agency ethics official on the NSC and became the senior ethics official on the NSC. On July 25, 2019, Alex Vindman listened to a phone call between Presidents Trump and Zelensky and was concerned by the contents, saying that he "did not think it was proper to demand that a foreign government investigate a U.S. citizen," and "was worried about the implications for the U.S. Government's support of Ukraine." Alex believed that the call would "undermine U.S. national security." Alex immediately reported the call to Y. Vindman, who was the lead ethics attorney and a deputy legal advisor. Vindman recognized the serious legal ramification of the call, including violations of law, and the legal/political jeopardy President Trump faced. Vindman advised that they both further report the call through channels to the NSC's lead counsel, John Eisenberg. Vindman had two more conversations with Mr. Eisenberg about the July 25, 2019 phone call. The first follow-up conversation occurred on August 1, 2019. Vindman sought to clarify with Mr. Eisenberg their role and obligations as attorneys, and whether as attorneys they were duty-bound to represent the Office of the President of the United States or the individual serving as President. Vindman had a second conversation with Mr. Eisenberg on August 5, 2019, when he conveyed his concern that President Trump's request that President Zelensky investigate President Trump's political rival may have violated the Federal Bribery Statute, the Foreign Corrupt Practices Act, and federal election laws. Once the call became public, both brothers received threats and denunciation, and reached out to the Army regarding their family's safety.

Beginning in 2012, Vindman became a Army Judge Advocate. In this capacity he served as a brigade judge advocate in Germany and senior trail counsel/ chief of justice for Fort Hood, Texas, at the time the busiest court martial judication in the world. As senior trial counsel, he tried 7 serious felony cases including kidnapping, sexual assaults, and fraud. Returning to Washington, D.C. he was then a senior labor attorney-advisor for the Department of the Army. Vindman was on the Army Staff at the Pentagon from July 2016 to July 2018.

Vindman is married to Cindy Vindman, née Groff. The couple has two children, a son born in 2004 and a daughter born in 2010. His identical twin is Lieutenant Colonel Alexander Vindman. Vindman has an older brother, Leonid Vindman, who also served in the Army.

Vindman was elected mayor of Between, Georgia in 2001.

Vindman completed the Infantry Officer Basic Course (IOBC) at Fort Benning in 1998 and was sent to the 82D Airborne Division in Fort Bragg, NC, where he led both airborne infantry and airborne anti-armor platoons. In addition to an overseas assignment to Germany, Vindman is a combat veteran of the Iraq War. He served in Iraq from January 2011 to June 2011 in Operation New Dawn. He was promoted to the rank of major in 2006, to lieutenant colonel in 2016, and to colonel in 2021.

In 1997, Vindman graduated from the State University of New York at Binghamton in Binghamton, New York with a bachelor of arts degree in history. He took part in the Reserve Officers' Training Corps while in college and received a second lieutenant's commission in the Army's Infantry Branch in January 1997. He later received a master of science degree from Central Michigan University in General Administration, a Juris Doctor (JD) from the University of Georgia School of Law in 2006, and a Masters in Legal Letters (LLM) from the Judge Advocate Generals Legal Center and School (TJAGLCS).
