House Wants Four 'Big Tech' CEOs to Testify in Competition ProbeApple, Amazon, Alphabet and Facebook have been pushed to respond.

AHouse investigation into tech competitionmay have testimony from some of the biggest names in the industry — if they agree, at least.Axiosunderstandsthe Judiciary Committee has asked Apple, Alphabet, Amazon and Facebook to say if their CEOs will testify for the antitrust probe in July. The companies reportedly have until June 14th to answer. However, they might not have a choice regardless of their responses — the letters hint at possible subpoenas for testimony and relevant documents if the CEOs don't volunteer.

In statement, committee chair David Cicilline said the documents (which include responses to other probes) were "essential" to the investigation and that requests like this were part of the "appropriate process" to obtain the files.

While major tech CEOs havetestified for Congressin the past, their appearances aren't guaranteed. Companies have sometimes chosen to send other executives instead, and Amazon has so fardeclined to committo testimony from Jeff Bezos in another investigation. That's not including concerns about the ongoing pandemic, either. If they do agree, though, July could prove a pivotal month as politicians seek to keep tech giants in check.
