Rep. Elise Stefanik, R-N.Y. questioned Lt. Col. Alexander Vindman, an Army officer who works for the National Security Council, and Jennifer Williams, an aide to Vice President Mike Pence, on Nov. 19, in a public hearing as part of the impeachment inquiry into President Donald Trump. Vindman and Williams both listened in on a July phone call in which Trump asked the president of Ukraine to investigate former vice president and 2020 presidential candidate Joe Biden and his son, Hunter. Stefanik asked several questions about Hunter Biden's position on the board of Burisma, a Ukrainian gas company, in 2016. "Do you agree that Hunter Biden on the board of Burisma has the potential of the appearance of a conflict of interest?" Stefanik asked. "Certainly the potential," Vindman said. Williams also said yes.
