The as-yet-unnamed suspect killed in an attack that left one police officer dead and a second "severely" wounded was previously known to authorities and had been flagged as a extremist. Police have issued a warrant for a second suspect, who Reuters reports arrived in France from Belgium.

What we know about the attack:

  • A car pulled up alongside a police vehicle and a man "immediately" emerged and began firing.
  • Interior Ministry spokesman: "An automatic weapon was used against police, a weapon of war."
  • ISIS has claimed responsibility.
  • The massive police response included the closing of the Champs-Élysées.
  • France will go to the polls Sunday in the presidential election, with terrorism a top issue.

President Trump's choices to succeed Justice Ruth Bader Ginsburg are down to two women, both federal appeals court judges.

The frontrunners are Amy Coney Barrett of Chicago, the early favorite, and Barbara Lagoa, who is viewed as easier to confirm. The Senate confirmed Lagoa 80-15 last year, so many Democrats have already voted for her.

The CDC updated its guidance on Friday to acknowledge that the coronavirus can be transmitted through the air at distances farther than six feet and through "droplets or small particles, such as those in aerosols" like coughs or sneezes.

Why it matters: The update — which was little noticed until a CNN story was published Sunday — comes months after scientists pushed for the agency to acknowledge the disease was transmissible through the air. The CDC previously said that close person-to-person contact was the bigger concern.

Top Mueller prosecutor: "We could have done more"

Andrew Weissmann, one of former special counsel Robert Mueller's top prosecutors, says in his new book, "Where Law Ends: Inside the Mueller Investigation," that the probe "could have done more" to take on President Trump, per The Atlantic.

Why it matters ... Weissmann argues that the investigation's report didn't go far enough in making a determination regarding Trump's potential obstruction of justice: "When there is insufficient proof of a crime, in volume one, we say it. But when there is sufficient proof, with obstruction, we don’t say it. Who is going to be fooled by that? It’s so obvious."
