Obama didn't elaborate on what type of common sense gun laws he thinks should be enacted, but in the months before he left office, a regulation was put in place that added "people receiving Social Security checks for mental illnesses and people deemed unfit to handle their own financial affairs" to the national background database, according to NBC News. However, in February 2017, President Donald Trump signed a bill that rolled back the regulation.
In June 2017, a Quinnipiac poll revealed that 94 percent of individuals surveyed supported requiring background checks for all gun buyers, but according to the Associated Press, Cruz purchased the gun legally at a Broward County gun store.
Florida runs an instant background check on those purchasing guns, but he would have been able to easily pass the check because he had no criminal background. The check would not have picked up on his long history of being treated for mental illness.
Florida Governor Rick Scott said during a press conference Thursday that he would discuss increasing funding for mental illness services and keeping guns out of the hands of mentally ill with the Florida Legislature next week.
"If somebody is mentally ill, they can't have access to a gun," Scott said.
