Four academic experts, who haven't been identified, are now set to appear as witnesses during the House Judiciary's first impeachment hearing on Wednesday.
The report will serve as a guideline for the Judiciary Committee, with an initial hearing on "Constitutional Grounds for Presidential Impeachment" expected Wednesday.
Hearings before the committee, which has responsibility for crafting any formal charges against Mr. Trump, are a major step toward possible charges.

Last week, Brenda Lawrence (D-MI) proposed censuring the president rather than impeaching him but was quick to backtrack her comments after her words made it out of her district and into the ears of Democratic leadership.
One article, according to lawmakers and aides involved in the impeachment inquiry, is nearly certain to include what they consider is Trump's abuse of power surrounding his dealings with Ukraine - a situation that Schiff and others have called "bribery, " specifically stated as an impeachable offense in the Constitution. The House Judiciary Committee also plans to conduct hearings related to Special Counsel Robert Mueller's Russian Federation report and its findings.
Chairman Adam Schiff has previously stated that the report would be coming soon without providing a specific date.
In keeping with committee rules, panel members are expected to be able to review the report starting at 6 p.m. Monday, 24 hours before the scheduled meeting.More news: England's second Test chances rely on Joe Root flourishing
The impeachment probe is looking into whether Mr. Trump abused his power to pressure Ukraine to launch investigations of political rival Joe Biden and a discredited conspiracy theory promoted by Mr. Trump that Ukraine, not Russian Federation, interfered in the 2016 US presidential election.
Trump has claimed Democrats are conducting the inquiry without due process, but earlier this week Judiciary Chairman Jerrold Nadler, D-New York, invited Trump and his legal representatives to participate in the next wave of hearings.
The Dec. 4 hearing is set to take place following a series of public hearings and closed-door depositions started by the House Intelligence Committee in late September.
