Democrats are ramping up efforts to impeach President Trump for pressing the president of Ukraine to investigate Democratic presidential candidate Joe Biden and his son Hunter. Nearly 90% of House Democrats now support impeachment. On Thursday, a declassified version of a complaint by an anonymous whistleblower was released, detailing his concerns about Trump’s July phone call with Volodymyr Zelensky. In the complaint, the unnamed whistleblower — who has been identified as a CIA official — accused the president of “using the power of his office to solicit interference from a foreign country in the 2020 U.S. election.” The complaint also revealed details about how the White House attempted to “lock down” all records of Trump’s phone conversation with Zelensky by moving a transcript of the call to a standalone computer system reserved for codeword-level intelligence information. The whistleblower wrote in his complaint, “According to White House officials I spoke with, this was 'not the first time' under this Administration that a Presidential transcript was placed into this codeword-level system solely for the purpose of protecting politically sensitive — rather than national security sensitive — information.” For more on the unfolding scandal, we speak with James Risen, senior national security correspondent for The Intercept.
