The long summer recess for Congress is at last well and truly over. The House Judiciary Committee has ramped up for the fall season, issuing demands for huge piles of documentation from Apple, Amazon, Facebook, and Google as its antitrust probe into Big Tech grows.

The committee launched the bipartisan inquiry in June, seeking in part to determine "whether existing laws are adequate" to the task of regulating the sprawling tech titans that power the 21st century economy. As part of that probe, the committee has now issued lengthy requests for information to the four companies digging deeply into the question of competition.
