Former National Security Council staff member Fiona Hill and David Holmes, a political counselor at the U.S. Embassy in Ukraine, headlined the fifth day of public testimony in the House impeachment inquiry Thursday.

Hill, an expert on Europe and Russia, testified behind closed doors she was disturbed by President Trump’s alleged effort to pressure Ukraine into investigating his political rivals and that her boss, former national security adviser John Bolton, was disturbed as well. Hill told investigators Bolton characterized the effort as a “drug deal.”

Holmes told impeachment investigators he overheard a phone call between U.S. Ambassador to the European Union Gordon Sondland and President Trump, during which Trump asked Sondland about the status of investigations by Ukraine.

The impeachment hearings are trying to determine whether Trump tried to leverage $391 million in military aid to Ukraine and a White House visit by his Ukrainian counterpart for investigations into former Vice President Joe Biden, Biden’s son, Hunter, and a debunked conspiracy theory positing that Ukraine, not Russia, was responsible for 2016 U.S. presidential election interference.
