The top civilian official in the U.S. Army said the service isn’t investigating Lt. Col. Alexander Vindman, days after President Trump told reporters that the military may look into disciplining the former National Security Council official and key impeachment inquiry witness.

Army Secretary Ryan McCarthy said Friday there is no investigation into Vindman, who had been detailed to the White House National Security Council as Ukraine director and was due to return to the Army for a new assignment when Trump dismissed him early from the post last week. The president also removed his twin brother from his job as a lawyer for the NSC.

McCarthy, in response to a question during an event at the National Press Club in Washington, noted that Vindman was currently in a “bridging” assignment at the Department of the Army headquarters and would be heading to a senior service college for study this summer.

“There’s no investigation,” McCarthy said.

Vindman, a Purple Heart recipient, handled Ukraine issues for the NSC while Trump and his personal attorney Rudolph W. Giuliani pressured the country’s new leader to announce investigations into former vice president Joe Biden and the Democrats.

During his public testimony in the House impeachment inquiry, Vindman said he thought Trump’s demand that a foreign government investigate Biden and his son was improper.

Late last week, Trump dismissed Vindman and his brother, Lt. Col. Yevgeny Vindman, who was serving as a lawyer on the National Security Council, from their White House posts. Both officers remain in the U.S. Army.

On Tuesday, when asked about Alexander Vindman’s dismissal from the White House, Trump said that “the military can handle him.” Asked what that meant, Trump replied, “If you look at what happened, they’re going to certainly, I would imagine, take a look at that.”

McCarthy, however, said Friday that there was no such move to look into Vindman, who immigrated to the United States from Ukraine as a child and went on to become a decorated combat veteran in his two decades in the U.S. military.

David Pressman, a lawyer for Vindman, rejected the notion that Vindman did anything wrong, noting in a statement last week that his client spoke publicly only once, pursuant to a subpoena from the U.S. Congress, and served in his post honorably.

“There is no question in the mind of any American why this man’s job is over, why this country now has one less soldier serving it at the White House,” Pressman said. “LTC Vindman was asked to leave for telling the truth. His honor, his commitment to right, frightened the powerful.”

“The truth has cost LTC Alexander Vindman his job, his career, and his privacy. He did what any member of our military is charged with doing every day: he followed orders, he obeyed his oath, and he served his country, even when doing so was fraught with danger and personal peril,” Pressman added.

Trump’s former chief of staff, retired Marine Corps Gen. John F. Kelly, earned the president’s ire by defending Vindman in public remarks this week.

When Trump asked Ukraine’s president to investigate Biden and his son, who served on the board of a Ukrainian gas company, it amounted to hearing an illegal order for Vindman, Kelly said.

“We teach them, ‘Don’t follow an illegal order. And if you’re ever given one, you’ll raise it to whoever gives it to you that this is an illegal order, and then tell your boss,’ ” Kelly told an audience at a Drew University lecture series in New Jersey.

Trump shot back at Kelly on Twitter, saying he couldn’t have fired the former White House chief of staff “fast enough.” Trump said the retired four-star general was “way over his head.”
