Apple expanded its health care footprint yesterday with its latest Apple Watch, adding features that can monitor users' heart rates and also detect falls.

The CEOs of tech's four leading giants will defend their industry's growing concentration of power from critics on both right and left who view them as monopolists when they testify, most likely virtually, before Congress on July 27.

Why it matters: The joint appearance by Facebook's Mark Zuckerberg, Apple's Tim Cook, Amazon's Jeff Bezos and Google's Sundar Pichai will mark a historic collision between the leaders of an industry that has changed the world and political leaders who believe those changes have harmed democracy and individual rights.

The three topics generating the most intense interest online are the coronavirus, racial injustice and foreign policy, according to data from NewsWhip provided exclusively to Axios — and all are issues that are working against President Trump right now.
