House Democratic leaders warned the White House Wednesday to expect a subpoena demanding documents on President Donald Trump’s dealings with Ukraine, accusing the administration of “flagrant disregard” of previous requests and saying that refusal could be considered an impeachable offense. Separately, the Democrats accused Trump of “an incitement to violence” against a national security whistleblower and advised him and his administration not to intimidate potential witnesses in their impeachment inquiry. The whistleblower exposed a July phone call that Trump had with Ukrainian President Volodymyr Zelenskiy in which Trump pressed for an investigation of Democratic political rival Joe Biden and his family.
