President Biden told congressional leadership in a letter Saturday that this week's airstrike against facilities in Syria linked to Iranian-backed militia groups was consistent with the U.S. right to self-defense.

The Food and Drug Administration on Saturday issued an emergency use authorization for Johnson & Johnson's one-shot coronavirus vaccine.
Why it matters: The authorization of a third coronavirus vaccine in the U.S. will help speed up the vaccine rollout across the country, especially since the J&J shot only requires one dose as opposed to Moderna and Pfizer-BioNTech's two-shot vaccines.
