“When the impeachment inquiry started, a little more than three weeks ago, there were only an anonymous whistle-blower's complaint and the summary that Trump released of his July 25th phone call with the Ukrainian President. Because the investigation has moved so quickly, it is easy to lose sight of how much has been learned since then. Day after day, in fact, the House's impeachment inquiry has produced significant revelations that point directly to Presidential culpability. ...

”Ever since Democrats took control of the House in January, Trump has sought to block them from conducting investigations and oversight of his Administration, defying subpoenas, refusing to send officials to Capitol Hill, and fighting Congress in court. The impeachment inquiry, however, has finally breached the Administration's blockade. Just this past week, the fired U.S. Ambassador to Ukraine, Marie Yovanovitch; the former National Security Council senior director in charge of Ukraine policy, Fiona Hill; the current State Department deputy assistant secretary in charge of Ukraine policy, George Kent; the Secretary of State's senior adviser, who quit in protest over the Ukraine affair last week, Michael McKinley; and Sondland, a wealthy Trump donor turned E.U. ambassador, all testified, defying Trump in order to do so, and at considerable risk to their careers. ...

“‘The floodgates may have opened,’” said Hill's attorney Lee Wolosky.
