Ambassador Marie "Masha" Yovanovitch will testify today at the second public hearing in the impeachment inquiry into President Trump.
Yovanovitch -- "someone who has never been hungry for the spotlight," as one former State Department official described her -- has increasingly found herself there as new developments in the Ukraine controversy have come to light.

Diplomatic support: The diplomatic community has rallied behind Yovanovitch since the contents of Trump's call were disclosed, and some former diplomats have also called for the State Department and Secretary of State Mike Pompeo to lend their public support to the career foreign service officer.
Retired US Ambassador Nicholas Burns called for "the higher levels of the State Department" to "come out and defend her."
"They should say she was a good ambassador, she did what was asked. She did what her constitutional duty asked her to do, represent the United States ably and honorably," Burns told CNN. "She
