Committee Chairman Bennie Thompson told reporters Tuesday that a hearing scheduled for Sept. 28 would be the last for the committee, "unless something else develops." 

The panel is also planning to release an interim report of its investigative conclusions in early October, just weeks before the Nov. 8 elections that will determine control of Congress.

"It won't be a quiet period," Thompson, a Mississippi Democrat, said last week.

The panel will need to crank up the volume to regain attention seized by the FBI's raid of Trump's Mar-a-Lago estate in Florida and the dozens of subpoenas issued by federal and state grand juries. Since its last hearing, on July 21, the committee's vice chair, Republican Liz Cheney, suffered a deflating primary loss to a Trump-backed candidate in Wyoming.
