The former US ambassador to Ukraine, whom President Donald Trump called "bad news" before firing her, will be in the spotlight on Friday when she testifies at the second day of televised impeachment hearings.
The session before the House of Representatives Intelligence Committee, scheduled to begin at 9 am (1400 GMT), is part of the Democratic-led impeachment inquiry that threatens Trump's presidency even as he seeks re-election in November 2020.
Marie Yovanovitch was removed from her post as ambassador to Kiev in May after coming under attack by Trump's personal lawyer, Rudy Giuliani, at a time when he was working to persuade Ukraine to carry out two investigations that would benefit the Republican president politically.
Giuliani was trying to engineer Ukrainian investigations of Democratic presidential contender Joe Biden and the former US vice president's son Hunter, who had served as a board member for the Ukrainian energy company Burisma, as well as a debunked conspiracy theory embraced by some Trump allies that Ukraine, not Russia, interfered in the 2016 US election.
The focus of the impeachment inquiry is on a July 25 phone call in which Trump asked Ukrainian President Volodymyr Zelenskiy, who was elected in May, to open the investigations.
Democrats are looking into whether Trump abused his power by withholding $391 million in US security aid to Ukraine as leverage to pressure Kiev. The money, approved by the US Congress to help a US ally combat Russia-backed separatists in the eastern part of the country, was later provided to Ukraine.

Trump has denied any wrongdoing and calls the impeachment probe a sham.
The hearings may pave the way for the Democratic-led House to approve articles of impeachment - formal charges - against Trump. That would lead to a trial in the Senate on whether to convict Trump of the charges and remove him from office. Republicans control the Senate and have shown little support for Trump's removal.
Yovanovitch, who has worked for both Republican and Democratic administrations, told lawmakers behind closed doors on October 11 that Trump ousted her based on "unfounded and false claims by people with clearly questionable motives" after she came under attack by Giuliani. She also denied allegations by Trump allies that she was disloyal to him and said she did not know what Giuliani's motivations were for attacking her.
Yovanovitch said Giuliani's associates "may well have believed that their personal financial ambitions were stymied by our anti-corruption policy in Ukraine."
Trump called Yovanovitch "bad news" in the phone call to Zelenskiy and added that "she's going to go through some things," according to a White House summary. Zelenskiy told Trump: "I agree with you 100 per cent" that she was a "bad ambassador."
'Go big or go home'
In her private testimony to lawmakers, Yovanovitch also described how Gordon Sondland, the US ambassador to the European Union, had urged her to use Twitter to express support for Trump to save her job. "He said, you know, you need to go big or go home. You need to, you know, tweet out there that you support the president," she said.
Three more public hearings are scheduled for next week.
Democratic Representative Raja Krishnamoorthi, an Intelligence Committee member, said he hoped that Republican lawmakers treat Yovanovitch fairly.
"I hope that they treat her with the dignity she deserves, the respect that she deserves. By all accounts, she was an excellent member of the foreign service," Krishnamoorthi told Reuters.
Krishnamoorthi said the evidence suggested she was removed to make way for the Trump administration's "irregular channel" of diplomacy in crafting Ukraine policy personally beneficial to Trump in which Giuliani played a central role along with diplomats Sondland and Kurt Volker, as well as Energy Secretary Rick Perry.
The hearing comes a day after House Speaker Nancy Pelosi told reporters that Trump already had admitted to bribery in the Ukraine scandal.
"The bribe is to grant or withhold military assistance in return for a public statement of a fake investigation into the elections," Pelosi, the top Democrat in Congress, told a news conference.
Pelosi's comments could offer a preview of articles of impeachment Democrats might put forward.
Two other career US diplomats, William Taylor and George Kent, testified on Wednesday in the first public hearing, expressing alarm over the pressure tactics on Ukraine by Giuliani for investigations that would benefit Trump politically.
Taylor is acting US ambassador to Ukraine. His aide David Holmes, who Taylor said overheard a July 26 telephone conversation in which Trump asked Sondland about progress in getting the Ukrainians to do the investigations, is due to appear before lawmakers in a private session on Friday.
