House Democrats Ask Mulvaney To Testify In Impeachment Inquiry

The transcript discusses the impeachment inquiry involving Mick Mulvaney, who is believed to have significant knowledge about the alleged quid pro quo with Ukraine. Mulvaney initially confirmed the withholding of military aid to Ukraine for investigating Democrats but later retracted his statement. The inquiry was triggered by a phone call between President Trump and Ukraine's president, where Trump requested an investigation into Joe Biden and his son. The White House has advised officials not to participate in the inquiry, labeling it a witch hunt.
