During her speech at the Commonwealth Club in San Francisco Wednesday, Sen. Dianne Feinstein, D-Calif., urged video game makers to consider how their products are affecting America’s youth.

Video games play “a very negative role for young people, and the industry ought to take note of that,” Feinstein said, according to the Associated Press.

According to the report, Feinstein suggested that video game developers should take voluntary steps to stop producing products that glorify guns — before Congress starts getting involved.

“If Sandy Hook doesn’t do it, if the knowledge of these video games this young man played doesn’t, then maybe we have to proceed, but that is in the future,” she warned.
