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.

The big picture: The 74-year-old Cain, co-chair of Black Voices for Trump, attended President Trump's rally in Tulsa in June and did not wear a mask. Two days after he was said to have tested positive, Cain commented on a July 4 celebration at Mt. Rushmore, tweeting: "Masks will not be mandatory for the event, which will be attended by President Trump. PEOPLE ARE FED UP!"

In early April, most Americans — and nearly as many Germans and Swedes — thought the coronavirus pandemic would be behind them by the time summer was out.

Why it matters: Like swimming against the tide, the longer countries are stuck in the pandemic, the farther it seems to stretch out in front of them.
