An army officer who heard Trump's Ukraine call reported it. But he was silenced.

White House national security official Lt. Col. Alexander S. Vindman, a decorated Iraq war veteran, twice registered internal objections about United States President Donald Trump's dealings with Ukraine. His complaints were not seen favorably, as one would expect from the Trump administration, and he was "frozen out" from a number of relevant meetings and events, including a diplomatic trip to three countries under his jurisdiction: Ukraine, Moldova, and Belarus, The New York Times reports. The veteran is now set to deliver testimony in which he will reveal crucial details about Trump's quid pro quo transaction with the country and more.

Lt. Col. Vindman claimed he was acting out of a sense of duty to his country. "I am a patriot," he affirmed. "And it is my sacred duty and honor to advance and defend our country irrespective of party or politics." The colonel believed that the investigation the Trump administration had urged Ukraine to undertake would undermine national security. He explained, "I did not think it was proper to demand that a foreign government investigate a United States citizen [Joe Biden's son Hunter biden], and I was worried about the implications for the United States government’s support of Ukraine. I realized that if Ukraine pursued an investigation into the Bidens and Burisma it would likely be interpreted as a partisan play which would undoubtedly result in Ukraine losing the bipartisan support it has thus far maintained... This would all undermine US national security."

The veteran is in an especially unique position as he is a Ukrainian-American immigrant who received a Purple Heart after being wounded in Iraq by a roadside bomb. Therefore, as an expert on the matter of national security and diplomacy, The New York Times asserts that it would be difficult to dismiss his testimony unlike his civilian counterparts'. Though he is not the initial or the secondary whistleblower, he did convey key details about the issue which prompted the Democrats to begin their impeachment investigation. Crucial elements about the case will become clearer upon the delivery of his testimony, it is believed.

In an even more damning move, he plans to testify that he contacted United States ambassador to the European Union Gordon D. Sondland about his "inappropriate" statements the day the envoy discussed during a White House meeting with Ukrainian officials about “Ukraine delivering specific investigations in order to secure the meeting with the president.” His draft statement reads, "Ambassador Sondland emphasized the importance that Ukraine deliver the investigations into the 2016 election, the Bidens, and Burisma... I stated to Ambassador Sondland that his statements were inappropriate [and that the] request to investigate Biden and his son had nothing to do with national security, and that such investigations were not something the NSC was going to get involved in or push."

As the investigation into Trump's impeachment swiftly surges forward, Lt. Col. Vindman's testimony will be monumental if the Democrats hope to secure impeachment prior to the 2020 Presidential Elections. The veteran affirmed, "On many occasions, I have been told I should express my views and share my concerns with my chain of command and proper authorities. I believe that any good military officer should and would do the same, thus providing his or her best advice to leadership." Once he delivers his testimony later this week, it will be time for the Democrats to execute their best acts of leadership.
