Given all the data Facebook collects and its barrage of data controversies in 2018, expect the social network to be under a microscope this year.

Background: Democrats have already signaled they’re serious about pushing some data privacy legislation as they take back the House this month. Republicans won't be sitting on the sidelines. 

Missouri’s Republican Sen.-elect Josh Hawley, who initiated an investigation into Facebook’s data practices as the state’s attorney general, tells Axios' David McCabe: 

"I highly doubt that many members of the public understand the breadth, in fact probably zero members of the public understand the breadth [of Facebook’s data collection]. The data collection is massive, it is largely unknown by consumers, and what particularly concerns me is the distinct possibly — I think probability — that consumers have not consented to this collection."

ICYMI: Just 2 weeks ago, D.C.’s attorney general sued Facebook for allegedly misleading consumers about its data sharing practices.  

  • And there's pressure on the Federal Trade Commission to act, with governments in Europe and elsewhere also eager to have a say.

America's coronavirus outbreak is slowing down after a summer of explosive growth.

By the numbers: The U.S. is averaging roughly 52,000 new cases per day — still a lot of cases, but about 10.5% fewer than it was averaging last week.

We're doing a lot less coronavirus testing

Data: The COVID Tracking Project; Chart: Andrew Witherspoon/Axios

The U.S. is cutting back on coronavirus testing. Nationally, the number of tests performed each day is about 17% lower than it was at the end of July, and testing is also declining in hard-hit states.

Why it matters: This big reduction in testing has helped clear away delays that undermined the response to the pandemic. But doing fewer tests can also undermine the response to the pandemic.
