The whistleblower whose complaint about President Trump’s communications with Ukraine launched House impeachment proceedings was still attending White House meetings recently and may have spoken to Lt. Col. Alexander Vindman prior to filing the complaint, according to the Washington Post.

On Saturday, the outlet published details about the steps a CIA analyst took to blow the whistle after the president urged Ukrainian President Volodymyr Zelensky during a July 25 phone call to start an investigation into former Vice President Joe Biden, who is also leading the pack of 2020 Democrats. Notably, the Post was clear that the whistleblower is male.
