WASHINGTON (AP) — Newly ascendant House Democrats are promising congressional action on gun control. This comes amid a rash of mass shootings, including a late-night assault at a California bar that killed 12 people.

Measures including expanded background checks and a ban on assault-style weapons are likely to reach the House floor when Democrats retake control after eight years of Republican rule.

The measures could win approval in the House but will face opposition from the Senate.
