The House impeachment hearings may damage Trump politically, but the proceedings seem to be helping his party financially.
Yet the witness accounts left one prominent hole that offered a lifeline for Mr Trump and his Republican allies. Citing executive privilege, both men have filed court cases to determine if they must appear. Putin, she said, deploys millions of dollars to "weaponize our own political opposition research and false narratives". Our nation is being torn apart.
"She said bad things about me", Trump said.
"This is a fictional narrative that has been perpetrated and propagated by the Russian security services themselves", said Hill, who until July served as the director for European and Russian affairs at the White House National Security Council.
"He was running a personal domestic political errand, we were concerned with national security", she said.
A trial, he said, would give Republicans a chance to question Rep. Adam Schiff, D-Calif., who led the hearings as chairman of the House intelligence committee.
As the hearing proceeded, Republican lawmakers asked fewer questions of Hill and Holmes and used their allotted time to instead make speeches.
US intelligence agencies and former Special Counsel Robert Mueller have determined that Russian Federation interfered in the 2016 election with a campaign of hacking and propaganda meant to sow discord in the United States, boost Trump's candidacy and harm his Democratic opponent Hillary Clinton.
"Are you insinuating that some of these witnesses are lying when you say that this is entirely political?" asked reporter Kayla Sullivan. If you're not familiar (I envy you), the theory's supporters claim that it was Ukraine, not Russian Federation, that meddled in the 2016 presidential election.
"Can I actually say something?" she eventually asked in her north-eastern English accent after a speech from Representative Brad Wenstrup, an ardent defender of President Donald Trump who was chiding her for her opening statement faulting those who push a false narrative that Ukraine, not Russian Federation, sought to meddle in the 2016 election.
There are indications that at least one Ukrainian politician expressed support for Clinton in 2016 on social media. But she said she is "very concerned about Russia's meddling in our 2016 elections".
Trump immediately rubbished the claim on Twitter.
Ambassador Gordon Sondland testified this week he shared with Vice President Mike Pence his concerns about the delay in military aid to Ukraine.
Hill had a front row seat to some of Trump's pursuits with Ukraine during her tenure at the White House.
Ian Kelly, the former USA ambassador to Georgia, tweeted in Yovanovitch's defence, saying: "Our official White House portraits did not arrive at Embassy Tbilisi until March 2018". The money - approved by the U.S. Congress to help Ukraine combat Russia-backed separatists in the eastern part of the country - was provided to Ukraine in September only after the controversy spilled into public view. Trump also repeated claims that Obama administration officials spied on his campaign and underscored the need to keep Republicans unified against impeachment.
Though pointed in some of her exchanges with GOP lawmakers, Hill was at other moments disarming. She said she didn't feel it would help "in keeping with my role as ambassador and a Foreign Service officer". Hill, a naturalized USA citizen, is originally from England.
The Republican president took issue with testimony on Thursday by David Holmes, a U.S. embassy official in Ukraine. And though Hill didn't expressly say this, no one plays into what Russian Federation wants more than does Trump himself.
Representative Will Hurd, a moderate Texas Republican who is retiring after his current term, announced that he considered Trump's conduct "inappropriate" but not impeachable.
"I hate to say it, but often when women show anger it's not fully appreciated", Dr Hill said.
