Ambassador Taylor’s testimony is the latest startling addition to the mounting evidence uncovered by the House impeachment inquiry as it looks into President Trump’s efforts to get the Ukraine to investigate Vice President Joe Biden. These revelations are precisely why the impeachment inquiry is essential, and make clear why the White House has been stonewalling every effort to investigate its actions.

It is clear that Ambassador Taylor, a career diplomat who has worked for both Republican and Democratic administrations, was stunned by the actions of the Trump White House as it attempted to strong-arm the Ukrainian government into investigations to advance President Trump’s political ambitions. The Ambassador will likely be attacked by President Trump’s supporters, but America owes him a debt of gratitude for his testimony and his service to the nation.

Following the House’s closed-door impeachment inquiry depositions, necessary to safeguard classified information that witnesses might share, the House should hold public impeachment investigation hearings to bring the full truth to the American people.
