US President Donald Trump's expected acquittal in his impeachment trial will be a hollow victory if the trial does not call any witnesses, top
Senate Democrat Chuck Schumer said Friday.

"This country is headed towards the greatest cover-up since Watergate," Schumer said ahead of what could be the final day of the historic hearings.
Schumer appeared resigned to Trump being acquitted by the Republican-controlled Senate on charges of abuse of power and obstruction of
Congress, after
Democrats looked set to fail to convince enough
Republicans to side with them on calling witnesses.
