The U.S. House Judiciary Committee this week sent letters to Apple, Alphabet, Amazon and Facebook asking whether their CEOs plan to participate in a series of antitrust hearings slated for July.
With the correspondence, antitrust investigators are pressing executives to testify on their own accord as part of a probe into the business dealings of Silicon Valley tech giants, Axios reports.
The letters raise the specter of potential subpoenas for testimony and document production in cases of noncompliance, the report said. Lawmakers have for months urged executives to testify on behalf of their respective companies as part of a review process that could inform changes to U.S. antitrust law.
