The House has released the transcript of their deposition with Fiona Hill, who served as the White House's top expert on Russia and Eastern Europe: docs.house.gov/meetings/IG/IG…
The House has also released the transcript of its deposition with Alex Vindman, a National Security Council official who was on the line for Trump's July 25 call with Volodymyr Zelensky: docs.house.gov/meetings/IG/IG…
To Vindman, the meaning of Trump's call with Zelensky was immediately apparent: It was a "demand" for Zelensky to investigate Trump's political opponent in exchange for a face-to-face meeting. intelligence.house.gov/uploadedfiles/… 
He also testified that Sondland clearly delineated Trump's demands: "There was no ambiguity ... He was calling for something, calling for an investigation that didn’t exist into the Bidens and Burisma." intelligence.house.gov/uploadedfiles/…
Vindman also detailed what was left out of the "transcript" released by the White House, which he says included a discussion showing a clear understanding that "Burisma" was Trump's code for the Bidens. intelligence.house.gov/uploadedfiles/…
He also suggests the White House's hold on military aid came earlier than has been previously reported, saying he knew of it as early as July 3, more than two weeks before the OMB reported the hold to other government agencies. intelligence.house.gov/uploadedfiles/…
Vindman testified that he drafted a memo explaining that the "consensus view" of the U.S. government was that the aid should be released—but the hold stayed on for more than a month. intelligence.house.gov/uploadedfiles/…
And, as the whistleblower complaint first revealed, Vindman testified that the White House went out of its way to bury the records of the July 25 call in a different system than it normally used. intelligence.house.gov/uploadedfiles/…
According to Hill, in a meeting with Ukrainian officials, Sondland "blurted out" that there was "an agreement with the Chief of Staff for a meeting if these investigations in the energy sector"—in other words, into Burisma—"start." intelligence.house.gov/uploadedfiles/…
It wasn't a one-time event—Hill testified that Sondland repeated the trade-off the next day, and even specifically mentioned Burisma. intelligence.house.gov/uploadedfiles/…
Even John Bolton was uncomfortable with the quid pro quo—especially after Giuliani repeatedly clarified in the press what the real goal of the investigations was. intelligence.house.gov/uploadedfiles/…
Hill was "shocked" and "saddened" to read the July 25 call transcript, which in her view clearly showed the president demanding investigations of debunked conspiracy theories about his opponents. intelligence.house.gov/uploadedfiles/…
The call "really was kind of [Hill's] worst fears and nightmares:" Trump was subverting the national security process, dangling a White House meeting in exchange for investigations that served his personal political interests. intelligence.house.gov/uploadedfiles/…
In Hill's view, there was no national security re

Hill also forcefully rejected Trump and his Republican accomplices' conspiracy theories that Ukraine meddled in the 2016 election: intelligence.house.gov/uploadedfiles/…
