DeVos, in a radio interview Thursday morning with conservative radio host Hugh Hewitt, did not offer any policy prescriptions but said the latest shooting should spur “much more robust conversation around tracking and tackling mental health issues.”“Congress needs to be holding hearings on these issues and we’ve seen lots of discussion on this every time we’ve had an incident,” DeVos said. “We need to have a conversation at the level where lawmakers can actually impact the future.”
