2020 Democratic presidential candidate former Vice President Joe Biden visited Iowa over the weekend along with several other Democratic candidates stumping for votes just days ahead of tonight's Democratic debate.
As expected, a hot topic of discussion was the Democrats' impeachment inquiry and
President Trump's allegations that Biden engaged in quid pro quo by way of
using his position as vice president in 2016 and a billion dollars in U.S. loan guarantees to have the Ukrainian prosecutor
fired for investigating Burisma Holdings. Biden's son Hunter sat on the Burisma board member at the time.
