A current State Department official and one former one are slated to testify Tuesday to provide more context and corroborate details from other witnesses about the Trump administration’s policy toward Ukraine, including ex-national security adviser John Bolton’s wariness of the president’s personal lawyer Rudy Giuliani.
Catherine Croft, special adviser for Ukraine at the State Department and a former national security council expert on Ukraine, and Christopher Anderson, an assistant to former special envoy to Ukraine Kurt Volker, are expected to appear in closed session today, according to an official working on the impeachment inquiry. Volker was questioned earlier in the investigation.
