Will Senate Dems, GOP play swapsies for witnesses? Unlisted Video

US Senators are expected to vote on Friday on whether to call witnesses to testify in President Donald Trump's impeachment trial.
According to Business Insider, Democrats are pushing to hear from four key witnesses.
Among them are acting White House chief of staff Mick Mulvaney and former national security adviser John Bolton.
The majority of Republicans oppose calling witnesses.
However, if at least four defect, many will demand to hear from Hunter Biden, whom Trump wanted Ukraine to investigate.
But Senate Minority Leader Chuck Schumer argues that if Republicans call Biden to testify it'll prove Trump's request was political.
And most Dems say the Bidens' actions are a distraction from the president's alleged abuse of power and obstruction of Congress.
