AFTERNOON WITNESSES: WHO ARE THEY?
There are two witnesses testifying this afternoon.
One is Kurt Volker. He's the former US special envoy to Ukraine and one of the so-called "three amigos" who were given special authority over American relations with the Eastern European country. European Union Ambassador Gordon Sondland and Energy Secretary Rick Perry make up the rest of the trio. Volker has denied participating in efforts to unearth damaging information on former Vice President Joe Biden, but he's provided text messages to Congress that show he talked to officials in Ukraine that President Trump had wanted, according to CNN.
The other witness is Tim Morrision who was a Russia expert with the White House's National Security Council. Morrision is important because he listened to Trump's July phone call with Ukraine's president and had important exchanges with Sondland about military aid for Ukraine, the Washington Post said.
