Congress is poised to approve $25 million in gun violence research as part of its year-end spending deal due Friday.

The sum is half what Democratic leaders requested, but it would be the first time in two decades that the Centers for Disease Control and Prevention would receive direct funding to look into the issue. The funding is part of the deal Congress must pass by Friday to avoid a government shutdown, with half of the money going to the CDC and the rest going to the National Institutes of Health, which provide grants to scientists.
