Hoffman said he expects to encounter opposition in his push for gun safety legislation, but he will stand by his ideas. In that case, a federal court determined it was okay to restrict access to a targeted group for the sake of public safety.

Scott's office announced that the Republican governor will sign both bills on Sunday. "I know there's lots of things in there that are a start, and there's in there that's going to bring some pieces back together for Parkland".
Scott also plans to approve a bill that revamps Florida's universities and colleges and includes a significant boost in financial aid provided to the state's top performing high school graduates.
