The pace of impeachment-related revelations is breathtaking, and it isn't slowing yet. With each day comes yet another executive branch staffer defying the White House by testifying behind closed doors on Capitol Hill — new names, fresh allegations, and ever more twists and turns. To help us follow the developments, Brian Lehrer — whose office here at WNYC is mere steps away from OTM HQ — has started a daily podcast: Impeachment. In this second episode of the podcast, New York Times reporter Katie Benner explains why George Kent, a senior State Department official for Ukraine policy, told Congressional investigators that he was instructed by a supervisor to "lie low" after raising concerns about the Trump administration's conduct.
