"We must do more to protect our children", Trump continued, adding that school safety is now a top priority of his administration. She said a federal age limit for the purchase of those weapons may also be discussed.

He will continue to meet with state and local law politicians, as well as law enforcement representatives, White House Press Secretary Sarah Huckabee Sanders said during her televised briefing Tuesday.
"We can not merely take actions that make us feel like we are making a difference", Trump said.
Meanwhile, survivors of the Parkland high school shooting launched a campaign under the tag #NeverAgain, urging the United States government to ensure the saftey of the nation's schools.
Trump was scheduled to host a listening session Wednesday with high school students and teachers from the Florida school, and from other schools that suffered similar attacks, such as Sandy Hook Elementary in Newtown, Connecticut. Former student Nikolas Cruz was charged with killing 17 people and wounding another 15 after opening fire with his AR-15 rifle.
There have been increased calls from Democrats and activists to tighten gun-control laws in the wake of the Florida shooting.
"We will be working very, very hard on that frightful, disgusting issue that took place last week in Florida", Trump said at an event on Tuesday. His political base of Republican voters overwhelmingly disapprove of most gun control actions and the President has enjoyed the support of the NRA.
Repeatedly during the 2016 Presidential campaign candidate Trump had made direct promises to American gun voters that he supports the Second Amendment and promised to protect it at all cost.
