U.S. President Joe Biden has signed a landmark gun control bill passed this week with bipartisan support.
It's a measure seen as the most sweeping gun violence bill passed in almost 30 years, and signing it on Saturday, President Biden said it'll save lives.
The new law strengthens background checks for gun buyers under 21, and will ban gun buying for people with a recent record of domestic violence against intimate partners even if they aren't married.
It'll also help states pass laws that can get weapons out of the hands of people deemed to be a threat to themselves or others.
The bill was prompted by two mass shooting this year in particular one at a grocery store in New York and another at an elementary school in Texas.
