(CNN) House Judiciary Chairman Jerry Nadler will authorize a subpoena this week to obtain the full, unredacted report from special counsel Robert Mueller, teeing up a showdown between congressional Democrats and the Trump administration over the nearly 400-page report.

Nadler said Monday that he had scheduled a markup on Wednesday to authorize a subpoena for the Mueller report, as well as the special counsel's underlying evidence. The markup would give the New York Democrat the green light to subpoena the report, though Nadler has not said whether he would do so before Attorney General William Barr releases a redacted version publicly, which he is expected to do later this month.

The House Judiciary Committee will also vote to authorize subpoenas for five former White House staffers — Don McGahn, Steve Bannon, Hope Hicks, Reince Priebus and Ann Donaldson — whom Nadler says may have received documents from the White House relevant to the special counsel's probe and the committee's investigation that would waive executive privilege.

The subpoena markup is scheduled one day after the April 2 deadline Democrats set for Barr to provide the full Mueller report and its underlying evidence to Congress.

Barr sent Nadler and Senate Judiciary Chairman Lindsey Graham a letter on Friday stating that he was working with Mueller to finish redactions of the report before making it public by "mid-April, if not sooner." Barr said he was redacting four types of materials from the report: grand jury material, sensitive intelligence material, information from ongoing investigations and information that would "unduly infringe on the personal privacy and reputational interests of peripheral third parties."
