Adam Schiff appears very bitter that President Donald Trump has fired Michael Atkinson, the Intelligence Community Inspector General. He's the guy who told Congress that there was a few "whistleblower" concerns with a phone call between Donald Trump and President Volodymyr Zelensky of the Ukraine.
Daily Caller says Atkinson is the man "who precipitated an impeachment inquiry when he relayed anonymous whistleblower testimony that the president’s conversation with Zelensky sought an investigation into former Vice President Joe Biden in return for delivering military assistance."
Adam Schiff says Trump is firing people in the middle of the night in retaliation.
Trump does not like Adam Schiff, so is expected that Trump could likely issue a statement on Twitter about Schiff's response.
