Army Officer Says He Raised Concerns About Trump and Ukraine Associated Press WASHINGTON - A military officer at the National Security Council twice raised concerns over the Trump administration's push to have Ukraine investigate Democrats and Joe Biden, according to testimony the official is to deliver Tuesday in the House impeachment inquiry. Alexander Vindman, an Army lieutenant colonel who served in Iraq and, later, as a diplomat, is prepared to tell House investigators that he listened to President Donald Trump's July 25 call with new Ukraine President Volodymyr Zelenskiy and reported his concerns to the NSC's lead counsel. "I was concerned by the call," Vindman will say, according to prepared testimony obtained Monday night by The Associated Press. "I did not think it was proper to demand that a foreign government investigate a U.S. citizen, and I was worried about the implications for the U.S. government's support of Ukraine." Vindman is the first White House official who listened in on that call to testify as the impeachment inquiry reaches deeper into the Trump administration and Democrats prepare for the next, public phase of the probe. He's also the first current White House official to appear before the impeachment panels. The inquiry is looking into Trump's call, in which he asked Zelenskiy for a "favor" -- to investigate Democrats -- that Democrats say was a quid pro quo that could be an impeachable offense.
