Republicans are hoping a report that Hunter Biden offered to set up a meeting between his then-vice president father and a top executive from the Ukrainian energy company central to President Trump’s impeachment will upend the White House race 20-odd days before the election.

Hunter Biden allegedly suggested Burisma Holdings Limited’s Vadym Pozharskyi speak with his father in 2015 when the younger Biden was being paid $50,000 a month to be a member of the oligarch-linked firm’s board, according to the New York Post Wednesday. The Democratic presidential nominee has denied ever meeting Pozharskyi, echoing a statement from his son’s lawyer that the accusations were tied to “widely discredited conspiracy theories.”
