Some are situational and temporary, such as his argument that the process was illegitimate because it hadn't been authorized by a vote of the full House (which it now has been).
Volker worked with Trump attorney Rudy Giuliani, the White House and Ukrainian officials to arrange the July 25 phone call between Trump and Ukrainian President Volodymyr Zelensky and a potential White House visit by Zelensky while pushing for investigations into Trump's political foes. Amid the blows raining down on the administration, there have been comments that give the president a degree of cover. The bribery plot, as Sondland described it, included a September 1 trip to Warsaw to deliver the quid pro quo message to the Ukrainians: Military aid would be withheld until Trump got his kickback.
Both men were dismayed by Mr. Trump's delegation of decisions about Ukraine to Mr. Giuliani, who was spreading false conspiracy theories about Mr. Biden and the US ambassador in Kyiv, Marie Yovanovitch, whom Mr. Trump ordered recalled. "And [Ukraine Finance Minister] Danyliuk, at least, understood and I'm sure that he briefed President Zelensky".
At a closed-door lunch on November 5, Pence told Senate Republicans the funds were being withheld over concerns that the Europeans weren't contributing enough aid and issues of corruption in Ukraine, according to a person familiar with the meeting but unauthorized to discuss it and granted anonymity.
"On Wednesday, November 13, 2019, we will hear from William Taylor and George Kent", Schiff continued.
The Intelligence Committee will hold the first open hearings of the Democratic-led impeachment inquiry next week, with three diplomats who've provided key closed-door testimony in the Ukraine controversy set to appear.
United States diplomat Gordon Sondland told a Ukrainian official his country would likely not get almost $400 million in security aid unless they pursued investigations demanded by President Donald Trump, revising earlier testimony to the Trump impeachment inquiry.
"I want nothing. I want no quid pro quo", Trump said, according to Sondland. So why did he tell the Ukrainians that there was one? Yovanovitch, who was ousted in May at Trump's direction, told investigators she had been told to "watch my back" and that people were "looking to hurt" her.
Other witnesses have said that Mulvaney was responsible for freezing the Ukraine aid in mid-July, and that he told others it was done at Trump's command.
"What I know", he said, "is that the direction was coming from Giuliani".
Trump has denied wrongdoing and accused Democrats of unfairly targeting him in hope of reversing his surprise victory in the 2016 presidential election. It depends on who you talk to.
Even the president himself, citing something he claimed to see on Fox News, published a tweet celebrating Sondland for having "said there was no quid pro quo". But he said Trump never withheld a meeting with Zelensky based on the demand for an investigation into the alleged interference.
However, in the revised testimony, Sondland said he recalled a September conversation in Warsaw with, as The Oregonian wrote, "a top Ukrainian adviser, Andriy Yermak, in which he made it clear that US aid was tied to a statement from the Ukrainians".
