Ousted US ambassador to testify in Trump impeachment probe

The House will hear from a singular witness Friday in the Trump impeachment hearings: Marie Yovanovitch, the former U.S. ambassador to Ukraine who was targeted by the president’s allies in a “smear” campaign now central to the probe.

The career diplomat, who served both Republican and Democratic presidents, is expected to relay her striking story of being suddenly recalled by Donald Trump and told to “watch my back.” It was all part of a swiftly developing series of events that sounded alarms about the White House’s shadow foreign policy.

Friday is the second day of public hearings to consider removing America’s 45th president. Democrats and Republicans are hardening their messages to voters as they try to sway voter opinion amid a deeply polarized public.
