Colorado’s Democratic Governor Jared Polis signed new legislation Friday to help curb gun violence, five months after a mass shooting at an LGBTQ nightclub in Colorado Springs killed five people. The new laws raise the minimum age to buy firearms from 18 to 21, establishes a three-day waiting period for gun purchases, expands Colorado’s red flag law and makes it easier for gun victims to sue manufacturers. Gun rights groups have already sued over the first two measures.

Meanwhile, a federal judge temporarily blocked an Illinois assault weapons ban after plaintiffs claimed in a lawsuit the law violates their Second Amendment rights.
