Twitter temporarily prevented Donald Trump Jr. from tweeting and retweeting on Tuesday after the president's son shared coronavirus-related misinformation.

Why it matters: The 12-hour hold — set off by a video touting hydroxychloroquine — is one of the toughest moves yet against a member of the Trump inner circle by the social media platform.

  • Republican strategist Andrew Surabian, who first shared the news, called the decision "open election interference."
  • The message from Twitter shared by Surabian shows that Trump Jr. can still browse Twitter and access his direct messages but cannot tweet, retweet, follow or like anything for 12 hours. His timeline remains publicly accessible.

The big picture: President Trump also shared a video baselessly promoting hydroxychloroquine as a coronavirus cure that had previously been removed from Facebook, per the Washington Post.

  • The FDA ended the drug's emergency use authorization for coronavirus last month.
  • While the president's retweet was removed, no further action was apparently taken against his account.

Italy imposes regional lockdown as coronavirus cases spike

Much of Italy will be placed under a strict lockdown as of Friday in the most drastic steps the country has taken to fight the coronavirus since it led the world into lockdown nearly eight months ago.

The big picture: Italy managed to keep the spread of the virus largely under control for months after a brutal first wave. But like much of Europe, it's currently recording unprecedented daily case counts and scrambling to avoid a return to overcrowded hospitals and climbing death tolls in the coming weeks.

Air pollution connected to higher COVID-19 death rates

A new study of more than 3,000 counties in the U.S. finds a correlation between higher levels of particulate air pollution and higher death rates from COVID-19.

Why it matters: COVID-19 may be caused by the novel coronavirus, but the outcome of an infection is influenced by everything from age to race to the environment. Understanding the connection between disease and pollution can help us address those risks going forward.
