The CIA officer who filed the whistleblower complaint about President Donald Trump’s interactions with his Ukrainian counterpart first reported his concerns to the CIA’s top lawyer, who then shared his concerns with White House and Justice Department officials, The New York Times reported Thursday night. This means that by the time the anonymous whistleblower filed a formal complaint with the intelligence community’s inspector general about the White House effort to cover up the president’s wrongdoing, officials within the White House already knew there was an internal CIA dissenter. The CIA officer’s complaint centers on a July 25 phone call in which Trump asked Ukrainian President Volodymyr Zelensky to investigate Trump’s 2020 political rival Joe Biden and his son Hunter Biden shortly after Zelensky brought up the topic of U.S. military aid to Ukraine.
