President Joe Biden says “we have to act,” but prospects for any major changes were dim, for now, in the closely divided Congress.

In brief remarks responding to the shooting, Biden urged Congress to move quickly to close the loopholes in the background check system and also to ban assault weapons and high-capacity magazines.
