Windman testified that he was concerned about a July call between Trump and Ukrainian President Vladimir Zelensky, and he took those concerns from National Security Council lawyer John Eisenberg, who told him not to discuss the conversation, the source said.
Eisenberg's attorneys and the NSC moved the transcript of the call into a higher security system than what is commonly used for presidential talks, a solution that is among the problems investigating democratic impeachment.
Politico first reported that Eisenberg had told Vindman not to discuss the call.
Windman was one of two National Security Council officials to testify to intelligence, foreign affairs and closed-door committees this week. Windman told lawmakers that although he had taken care of the call in July, he testified that the rough transcript of the White House was mostly accurate. But he suggested two revisions to the census ̵

Windman also testifies that he is convinced that Trump is personally blocking. release of US security aid in Ukraine to force Ukraine to publish a public inquiry that could help Trump politically. Windman also believes there is a link between the Ukraine investigation and the meeting between the Trump and Zelenki people following a July meeting before Trump-Zelensky's call. Windman and former White House aide Fiona Hill have reported concerns about meeting Eisenberg, Windman said.
The White House refused to weigh in on Windman's testimony on Friday.
"We cannot comment on testimony we did not have to be in the room to hear," White House press secretary Stephanie Grisham said.
Tim Morrison, chief adviser to the National Security Council on Russia and Europe, testified Thursday that the concerns he had during the July conversation were leaking transcripts. But he does not think there is anything wrong or illegal in the call itself, according to his opening statement. Sources told CNN Thursday that Morrison was involved in discussions to move the call to a more secure system.
Eisenberg and National Security Council lawyer Michael Ellis were asked to testify in an investigation into Parliament's impeachment on Monday behind closed doors. It is unclear if both will appear.
