He is now striking a very different tone as he backpedals from his earlier demands for sweeping reforms. Trump tweeted on Monday, adding "On 18 to 21 Age Limits, watching court cases and rulings before acting".
The White House's formal release of a school safety agenda is an early step, as the president is also naming a commission to come up with more recommendations.
At a campaign rally in Pennsylvania Saturday, Trump mocked the idea of a commission to solve problems government should tackle head-on.
"They have great power over you people", Trump said on February 28, referring to the NRA while addressing a group of lawmakers at the White House.
Professor Olson, who is also a certified firearms instructor and former national NRA board member, thinks when it comes to mass school shooting like the one in Parkland, Florida, armed teachers are the best defense. "That doesn't make sense".
