The National Security Council sent a list of allegations about Lt. Col. Alex Vindman to the Pentagon after he testified before the House in impeachment proceedings against President Donald Trump, according to one person who has seen the document and two others briefed on it.
The Pentagon received the document, which alleged Vindman created a hostile work environment at the NSC, as he was on track to be promoted to colonel. The accusations outlined in it, if substantiated, would have kept him from moving up a rank in the Army, the people familiar with the document said. They said it was not the typical evaluation that military officers serving on the NSC are given when their temporary positions end and they are set to return to the Defense Department, as Vindman was scheduled to do about six months after this document was sent to the Pentagon.
