Trump Attacks Democrats Over Whistleblower Complaint Hearing Patsy Widakuswara WASHINGTON - Still seething over the whistleblower complaint that triggered a House of Representatives impeachment query, President Donald Trump returned to Washington on Thursday lashing out at congressional Democrats and the news media and darkly hinting at retribution for government officials who assisted the whistleblower in accusing the president of misusing his powers of office. Trump returned to the White House from several days in New York attending the U.N. General Assembly. He returned the same time the House Intelligence Committee was holding a hearing on the administration's delay in submitting the whistleblower's complaint to Congress. The complaint asserts that Trump in a July 25 phone call sought help from the new president of Ukraine in digging up dirt about former Vice President Joe Biden and his son that would hurt Biden's prospects of winning the Democratic presidential nomination and challenging Trump in 2020. Military assistance Trump instructed his chief of staff, Mick Mulvaney, to hold back nearly $400 million in military assistance for Ukraine at least a week before the call, according to The Washington Post, to put pressure on the Ukrainian leader --a claim Trump bitterly disputes. .
