A Senate panel announced Wednesday it will release an interim report on its investigation into Hunter Biden's work for the Ukrainian energy firm Burisma Holdings.

The report, to be released within the next month or two, will focus on what former Vice President Joe Biden knew about his son's service on the board of the corrupt firm.

"These are questions that Joe Biden has not adequately answered,” said Sen. Ron Johnson, chairman of the Senate Homeland Security and Governmental Affairs Committee, reported Politico.   MORE

"And if I were a Democrat primary voter, I'd want these questions satisfactorily answered before I cast my final vote," the senator said.
