Later today, Facebook will post its earnings for the first quarter of 2017, and expectations are mixed.

Controversies: Facebook's been grappling with the rise of "fake news" and graphic violence on its Facebook Live platform, but the controversies are unlikely to affect the company's ad business. Similarly to Google, whose revenue has been unaffected by advertiser backlash over its programmatic ads ending up on inappropriate videos, Facebook has been actively working to smooth over its image.

The bad news: Facebook's revenue growth is expected to start slowing down. The company warned us last year that it is running out of space in its service to put more adds. To be clear, Facebook's revenue will be greater than a year ago, but the growth will be slower. What's more, it historically sees a big bump in revenue in the fourth quarter, followed by a drop in revenue the following, so expect to see that again.

The better news: Though Facebook doesn't break out Instagram's numbers, the photo-sharing app has had a huge success with its take on Snapchat's Stories feature and is on the upswing. Facebook also has yet to roll out its mid-roll video ads, so it's not fully monetizing its video content yet. When it does, that should help boost its revenue.

Supreme Court clears way for first federal execution since 2003

The Supreme Court ruled early Tuesday that federal executions can resume, reversing a lower court decision and paving the way for the first lethal injection since 2003 to take place at a federal prison in Indiana, AP reports.

The big picture: A lower court had delayed the execution, saying inmates had provided evidence the government's plan to carry out executions using lethal injections "poses an unconstitutionally significant risk of serious pain."

More Republicans say they're wearing masks

Data: Axios/Ipsos poll; Chart: Andrew Witherspoon/Axios

Nearly two-thirds of Americans — and a noticeably increasing number of Republicans — say they’re wearing a face mask whenever they leave the house, according to the latest installment of the Axios-Ipsos Coronavirus Index.

Why it matters: A weakening partisan divide over masks, and a broad-based increase in the number of people wearing them, would be a welcome development as most of the country tries to beat back a rapidly growing outbreak.

Buildings are getting tested for coronavirus, too

Testing buildings — not just people — could be an important way to stop the spread of the coronavirus.

Why it matters: People won't feel safe returning to schools, offices, bars and restaurants unless they can be assured they won't be infected by coronavirus particles lingering in the air — or being pumped through the buildings' air ducts. One day, even office furniture lined with plants could be used to clean air in cubicles.
