On Capitol Hill, televised impeachment hearings are slated to begin Wednesday in the inquiry into whether President Trump withheld military aid from Ukraine to pressure the Ukrainian president to investigate his political rival Joe Biden and his son. It is only the third time in U.S. history there have been televised impeachment hearings. On Wednesday, the first two witnesses to testify will be George Kent, a deputy assistant secretary of state, and Bill Taylor, a former ambassador and the top U.S. diplomat in Ukraine.
