House Speaker Nancy Pelosi says senators will “pay a price” if they block new witnesses from testifying in President Donald Trump's upcoming impeachment trial. She says Americans expect a “fair trial”. The House expects to transmit the articles of impeachment against Trump this week. The Republican leader of the Senate, Mitch McConnell, wants a speedy trial without new witnesses. Trump was impeached on charges of abuse of power and obstruction of Congress over his actions toward Ukraine. Trump tweeted a derisive comment against Pelosi right before she appeared for a television interview Sunday morning.
