Washington and California, which originally appeared to be epicenters of the coronavirus outbreak in the U.S., have slowed their surges of new cases — although it can't be ruled out that California is just behind on testing.

Why it matters: These states were early adopters of stringent social distancing measures, and these policies appear to be making a difference. That should offer us all fresh encouragement to keep staying home and practicing good hygiene.

Yes, but: As Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, warned yesterday during a White House coronavirus briefing, the numbers nationwide will likely get worse before they get better.

  • The U.S. is still adopting social distancing policies state-by-state, and there's a lag between when these measures are implemented and when people who have already been exposed begin to experience symptoms.
  • It then takes a few days for some of these people to need to be hospitalized, and then a few more days for deaths to rise.
  • This pattern will keep repeating until the virus stops spreading, which will continue as long as sick Americans continue to interact with healthy ones. But if we all stay home, that spread can't happen.

The bottom line: "In the next several days to a week or so, we're going to continue to see things go up. We cannot be discouraged by that, because the mitigation is working and will work," Fauci said.

  • Remember that things looked really bad in Washington and California a few weeks ago, too.

Facebook is rolling out a new policy that will prevent U.S. news publishers with "direct, meaningful ties" to political groups from claiming the news exemption within its political ads authorization process, executives tell Axios.

Why it matters: Since the 2016 election, reporters and researchers have uncovered over 1,200 instances in which political groups use websites disguised as local news outlets to push their point of view to Americans.

Nationalism and authoritarianism threaten the internet's universality

Governments around the world, prompted by nationalism, authoritarianism and other forces, are threatening the notion of a single, universal computer network — long the defining characteristic of the internet.

The big picture: Most countries want the internet and the economic and cultural benefits that come with it. Increasingly, though, they want to add their own rules — the internet with an asterisk, if you will. The question is just how many local rules you can make before the network's universality disappears.

The Democratic fight to shape Biden's climate policy

Left-wing climate activists don't want Joe Biden getting advice from people with credentials they don't like — and they're increasingly going public with their campaign.

Why it matters: Nobody is confusing Biden with President Trump, and his climate platform goes much further than anything contemplated in the Obama years.
