The panel, which hopes to decide whether to recommend Trump's impeachment to the full House by year-end, will meet on Thursday to consider a resolution that Democratic panel aides said would better align the inquiry with formal ones of the past.
House Democrats have broadly ramped up investigation of Trump as they returned from summer recess on Monday and unveiled an inquiry into reports that he pressured Ukraine's government into assisting his re-election campaign.
The measure to be considered at 8 a.m.
EDT (1200 GMT) on Thursday would authorize panel Chairman Jerrold Nadler to designate committee and subcommittee hearings as impeachment proceedings.
It would also allow for aggressive questioning of hearing witnesses by committee attorneys, set procedures for reviewing grand jury material and allow the White House to respond in writing to evidence and testimony.
