The White House used its official Twitter account on Tuesday to criticise the judgement of National Security Council official Lt. Col. Alexander Vindman as he publicly testified about President Donald Trump's July phone call with Ukraine's president.

Vindman was appearing before the House Intelligence Committee to kick off the second week of public impeachment hearings. 

"What I heard was inappropriate and I reported it. I did so out of a sense of duty," Vindman told the committee. "It was improper for the president of the United States to demand a foreign government investigation of a US citizen and a political opponent.”
