WASHINGTON (AP) – House Democrats have taken their first concrete steps in the impeachment investigation of President Donald Trump, issuing subpoenas demanding documents from Secretary of State Mike Pompeo and scheduling legal depositions for other State Department officials. At the end of a stormy week of revelation and recrimination, House Speaker Nancy Pelosi framed the impeachment inquiry as a somber moment for a divided nation. Trump, for his part, insisted anew that his actions and words have been “perfect” and the whistleblower’s complaint about his comments to the leader of Ukraine might well be the work of “a partisan operative.”
