Republican elected officials in Congress are leading an impeachment investigation against the president. Republicans have questioned James Biden, 74, over a series of financial transactions that they say incriminate his brother, the Democratic president.
This investigation is brushed aside by the Democrats, who see it as political maneuvering in the middle of an election year. The right accuses Joe Biden, so far without conclusive proof, of having used his influence when he was vice-president to allow his family to conduct questionable business in Ukraine and China.
