WASHINGTON — The House Judiciary Committee plans to vote this week to formalize procedures for a growing impeachment inquiry, clarifying its investigative authorities and granting President Trump new due process, a draft resolution shows.

The Judiciary Committee took similar steps in the 1970s and 1990s when it conducted impeachment inquiries into Presidents Richard M. Nixon and Bill Clinton. Now, as then, Democrats believe the resolution, a copy of which was reviewed by The New York Times, will allow the panel to speed up its work and potentially elicit more information than it otherwise could about instances of possible obstruction of justice and abuses of power by Mr. Trump.

The development carries significant symbolic weight, as well.

Though the committee has already informed federal courts and the public that it is in the midst of a full-scale impeachment inquiry, the three-page resolution will be the first time lawmakers have recorded a vote to that effect. Committee leaders hope the move will send a signal to Congress and the White House that their investigation is not only proceeding but intensifying, even as the broader Democratic Party caucus remains divided over the merits of ultimately voting to impeach Mr. Trump.

Based on the committee’s investigative plans, the new procedures could be put to the test quickly in the coming weeks.
