When Congress resumes next week, Schiff is expected to send the report, compiled from 17 closed-door depositions and five public sessions, to the House Judiciary Committee, where Chairman Jerrold Nadler will soon begin hearings that are expected to result in articles of impeachment against Trump.

The House judiciary committee on Tuesday will hold its first public impeachment hearing part of a new phase of the investigation that will seek to determine whether the president's actions amount to "high crimes and misdemeanors" as provided for in the United States constitution.
Schiff said the evidence "conclusively shows" that Trump conditioned a White House meeting with Ukraine's new president and critical U.S. military assistance on Kiev announcing investigations that would help Trump's 2020 reelection campaign.
"It's in violation of the oath of office of a president of the United States, and we have to be clear that you can not use your power of the presidency to withhold funds to get a foreign country to investigate an American citizen for your own personal gain".
Schiff said the hearings were conducted "in a fair and open manner, and in a way that put the witnesses' own words and testimony front and center", though the Democrats have refused to allow President Trump's legal team to participate in and cross-examine the witnesses. At base, the President has a choice to make: he can take this opportunity to be represented in the impeachment hearings, or he can stop complaining about the process.
The White House did not immediately respond to a request for comment or respond to Nadler's letter. Many but not all of the transcripts from those sessions have been released and are now public.
The hearing aims to explain high crimes and misdemeanors, the constitutional grounds for impeachment, and how the evidence collected by numerous House committees applies.
Lawmakers in the Democratic-led House of Representatives spent the last two weeks publicly questioning witnesses including White House officials and diplomats over allegations that Trump abused the power of his office when he pressured Ukraine to launch investigations that would help him politically.
Along the way, investigators uncovered a "massive amount of evidence in short order", Schiff said in a letter to his colleagues Monday.
"The unusual fact with this investigation is that the most explosive evidence is the first we received: it was the President's protocol", said Rep. Peter Welch, D-Vt.
"The witnesses who have defied Congress at the behest of the president will have to decide whether their duty is to the country, or to a president who believes that he is above the law".
