Mostly academics will be testifying at Thursday's House Judiciary antitrust subcommittee hearing, which will reveal where its year-long investigation into Big Tech and competition is going, a source familiar with the matter told Axios.

Why it matters: The hearing is the next step following testimony from Facebook's Mark Zuckerberg, Google's Sundar Pichai, Amazon's Jeff Bezos and Apple's Tim Cook before the committee in July. A showing of academics and think-tank types signals the lawmakers are still sorting out competition theories and possible legislative fixes to perceived antitrust abuses.

Who's testifying:

  • Michael Kades, Washington Center for Equitable Growth
  • Christopher Yoo, Penn Law School
  • William Baer, Brookings Institution
  • K. Sabeel Rahman, Brooklyn Law School
  • Zephyr Teachout, Fordham Law School
  • Sally Hubbard, Open Markets Institute
  • Rachel Bovard, Conservative Partnership Institute
  • Tad Lipsky, George Mason University

The bottom line: The lineup includes some well-known voices who advocate for new antitrust laws to rein in tech giants, along with more conservative figures, some of whom are concerned more about content moderation than antitrust or may simply be less inclined to break up big companies.

Tech's biggest upcoming battles in 2020

The most consequential stories for tech in 2020 pit the industry's corporate colossi against the U.S. government, foreign nations, and the human needs of their own customers.

Why it matters: Today's tech giants own and operate the informational hubs that increasingly shape our public and private lives. That's putting their products and policies under greater scrutiny than ever before.

Sens. Tim Kaine (D-Va.) and Susan Collins (R-Maine) are forging ahead with a draft proposal to censure former President Trump, and are considering introducing the resolution on the Senate floor next week.

Why it matters: Senators are looking for a way to condemn Trump on the record as it becomes increasingly unlikely Democrats will obtain the 17 Republican votes needed to gain a conviction, Axios Alayna Treene writes. "I think it’s important for the Senate's leadership to understand that there are alternatives," Kaine told CNN on Wednesday.

Stark reminder for America's corporate leaders

Rosalind "Roz" Brewer is about to become only the second Black woman to permanently lead a Fortune 500 company. She starts as Walgreens CEO on March 15.

Why it matters: It's a stark reminder of how far corporate America's top decision-makers have to go during an unprecedented push by politicians, employees and even a stock exchange to diversify their top ranks.
