Gov. JB Pritzker on Monday signed the two bills into law, which he said will continue Illinois’ efforts to be among the most aggressive states in combating gun violence.

The Safe Gun Storage Act requires owners to keep weapons in a locked box around minors and at-risk individuals. Another bill requires law enforcement agencies to use a federal tracing system to track firearms.

Illinois Gov. J.B. Pritzker signed a pair of new gun laws on Monday, while the Trump administration has voiced opposition on other measures.
