Florida Gov. Rick Scott on Wednesday punted on questions about whether policymakers should take a stand on mental health and gun control, saying that "there's a time" to have such conversations.

"There's a time to continue to have these conversations about how through law enforcement, how through mental illness funding that we make sure that people are safe," Scott said at a news conference in Parkland, Fla.

Scott's comments came hours after a gunman opened fire in Marjory Stoneman Douglas High School in Parkland, leaving 17 people dead.

Scott, a Republican, has an "A+" rating from the National Rifle Association's Political Victory Fund.

The gunman was taken into custody on Wednesday. He was identified as 19-year-old Nikolas Cruz, a former student at the high school who had been expelled for disciplinary reasons.

After the shooting, gun control advocates and some Democratic lawmakers renewed calls for tightening gun laws, particularly for those with mental illnesses.
