Trump defends firing impeachment witness Alexander Vindman

US President Donald Trump has defended firing a senior official who testified against him at his impeachment trial, saying he was "very insubordinate".

In a series of tweets, Mr Trump said Lt Col Alexander Vindman, a top Ukraine expert, incorrectly reported the contents of a "perfect" phone call that was at the centre of his impeachment.

He also fired US envoy Gordon Sondland, who testified against him at the trial.

Mr Trump reportedly wants a staff shake-up after his Senate acquittal.

In a historic vote on Wednesday, senators decided not to remove America's 45th president from office on charges arising from his dealings with Ukraine.

On Friday, Lt Col Vindman was escorted from the White House hours before Mr Sondland, then US ambassador to the EU, said he had been advised that the president intended "to recall [him] effective immediately".

Lt Col Vindman's twin brother, Yevgeny Vindman, a senior lawyer for the National Security Council, was also sent back to the Department of the Army on Friday.

In his first official response to the firings, Mr Trump attacked Lt Col Vindman's reputation, as well as coverage by US broadcasters CNN and MSNBC. He intentionally misspelled MSNBC as "MSDNC", a reference to the Democratic National Committee (DNC).

"Actually, I don't know him, never spoke to him, or met him (I don't believe!) but, he was very insubordinate, reported contents of my "perfect" calls incorrectly, &. was given a horrendous report by his superior, the man he reported to, who publicly stated that Vindman had problems with judgement, adhering to the chain of command and leaking information. In other words, "OUT", Mr Trump wrote.

How did Vindman annoy Trump?

Testifying in Congress last November, Lt Col Vindman said he was "concerned" after hearing Mr Trump's "improper" phone call on 25 July last year with Ukrainian President Volodymyr Zelensky.

The call led to Mr Trump's impeachment in December by the House of Representatives for abuse of power and obstruction of Congress. Democratic lawmakers argued that the president had dangled US aid in exchange for political favours.

When asked how he had overcome his fear of retaliation in order to testify, Lt Col Vindman testified: "Congressman, because this is America... and here, right matters."

David Pressman, Lt Col Vindman's counsel, told the BBC: "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.

"The most powerful man in the world - buoyed by the silent, the pliable, and the complicit - has decided to exact revenge."

According to White House sources, Lt Col Vindman had been expecting a transfer, telling colleagues for weeks that he was ready to move back to the defence department, where he still holds active-duty soldier status.

Earlier on Friday, US Defence Secretary Mark Esper said his department welcomes back all of its personnel from assignment. "We protect all of our service from retribution or anything like that."

On Thursday, Mr Trump mentioned the Vindman twins in a tirade against his political enemies at the White House.

How did Sondland annoy Trump?

Mr Sondland was very clear in his testimony that a White House visit by President Zelensky was conditional on Kyiv launching investigations that could be politically helpful to President Trump.
