President Barack Obama unveiled sweeping proposals to curb gun violence, including calls for Congress to pass universal background checks and an assault-weapons ban, plus 23 executive actions that don't require congressional approval. Quotes about the proposals:
"I have no illusions about what we're up against or how hard the task is in front of us. ... We should do as much as we can, as quickly as we can. And we cannot let the perfect be the enemy of the good." — Vice President Joe Biden.
