[7][13] After the death of their mother, the three-year-old twins and their older brother, Leonid, were brought to New York City in December 1979 by their father, Semyon (Simon).

[6][7][18] 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 1999.

[23] Starting in 2023, Vindman took on roles as a Hauser Leader and Senior Fellow at the Harvard Kennedy School Center for Public Leadership.

[29][30] Vindman was subpoenaed to testify before Congressional investigators on October 29, 2019, as part of the U.S. House of Representatives' impeachment inquiry against Donald Trump.

[28] Vindman stated additionally that he was concerned by two events, both of which he objected to with senior officials in real time, and which he reported to the National Security Council's lead attorney.

The first event occurred at a July 10 meeting between Ukraine's then Secretary of National Security and Defense Council Oleksandr Danylyuk, and then US National Security Advisor John Bolton, at which Ambassadors Volker and Sondland, and Energy Secretary Rick Perry were in attendance, and at which Sondland asked Ukraine to launch investigations into the Bidens in order to get a meeting with President Trump.

I am grateful for my father's brave act of hope 40 years ago and for the privilege of being an American citizen and public servant, where I can live free of fear for mine [sic] and my family's safety.

Dad, my sitting here today, in the U.S. Capitol talking to our elected officials is proof that you made the right decision forty years ago to leave the Soviet Union and come here to United States of America in search of a better life for our family.

"[39] On February 7, 2020, Vindman told NSC colleagues he expected to leave the White House's National Security Council to return to the Department of Defense.

[42] Subsequent news reports indicated that Vindman had been chosen to attend the in-residence course at the United States Army War College during its 2020–2021 session.

[43] On February 10, 2020, Senate Minority Leader Chuck Schumer (D-NY) sent a letter in an apparent response to the removal 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".

[44][45] On February 13, Trump's former chief of staff, retired Marine General John Kelly, defended Vindman's actions and testimony.

Vindman's attorney, David Pressman, described "a campaign of bullying, intimidation, and retaliation" by the Trump administration as the reason for his client's retirement.

He accentuates that speaking out about the July 25 call between Donald Trump and Volodymyr Zelenskyy was not merely a decision, but a duty rooted in his citizenship and service in the armed forces.

[10] On November 8, 2022, the lawsuit was dismissed by Federal Judge James E. Boasberg, noting that "political hackery alone" isn't a violation of the law.

[57] After January 2022, Vindman served as a senior advisor for VoteVets and started directing the Vet Voice Foundation’s national security and defense think tank, the Institute for Informed American Leadership (IIAL).

[61] In 2022, with Daniel Lubetzky, Alexander Vindman became the co-chair of the Global Democracy Ambassador Scholarship, which helps Ukrainian students who pursue their undergraduate degrees in the United States and abroad.

[63] In March 2023, the Vindman brothers launched the project Trident Support, whose primary objective is to establish a weapon maintenance and training facility within Ukraine.

[67] In 2020, Vindman and his wife Rachel appeared in an advertisement [68] created by The Lincoln Project and VoteVets supporting Joe Biden's presidential campaign.

His identical twin brother, Yevgeny S. "Eugene" Vindman, is a retired Army lieutenant colonel and Judge Advocate General's Corps officer who was assigned as an attorney on the National Security Council staff handling ethics issues, until he was dismissed from that post on February 7, 2020, at the same time as Alexander was removed from his NSC post;[7][70][42] The Army promoted Yevgeny to colonel on March 16, 2021.

[71] The Defense Department inspector general found in May 2022 that the Trump administration unlawfully retaliated against Yevgeny for his role in revealing the Trump-Ukraine scandal.
