President Trump on Thursday called on both Ukraine and China to investigate former vice president Joe Biden and his son Hunter in relation to the younger Biden’s business dealings during the tenure of the former vice president.

He comments came as Kurt D. Volker, who resigned last week as the Trump administration’s special envoy for Ukraine, was being interviewed behind closed doors in front of three House committees, accelerating the Democratic-led impeachment inquiry.

Volker was among the officials mentioned by name in the whistleblower report raising concerns about Trump’s July phone call in which Trump pressed Ukrainian President Volodymyr Zelensky to investigate former vice president Joe Biden and his son.
