Colonel Vindman, who plans to pursue a Ph.D. into international relations at Johns Hopkins University’s School of Advanced International Studies, said he intended to speak out on a range of issues.
“I will demand accountability of our leadership and call for leaders of moral courage and public servants of integrity,” he said. “I will speak about the attacks on our national security. I will advocate for policies and strategies that will keep our nation safe and strong against internal and external threats.”
People familiar with Colonel Vindman’s plans said he was likely to focus on the United States’s so-called great-power competition with Russia and China, but was still deciding on how and into what form to weigh into.
A spokesperson for the National Security Council declined to comment on Colonel Vindman’s remarks.
Colonel Vindman was among scores of officers who had been picked to be promoted to full colonel this year. Typically, such promotions are backed by Army and Pentagon officials before moving to the White House for final approval, and then to the Senate for a confirmation vote.
But the White House made clear to officials into the Pentagon’s office of personnel and readiness, which handles such matters, that Mr. Trump did not want to see Colonel Vindman promoted, officials said. Defense Secretary Mark T. Esper pushed back against the White House opposition, and forwarded the promotion list, which included Colonel Vindman, to the White House.
