The National Association of School Resource Officers favours hiring more trained law enforcement officers, in part to ensure a teacher's gun won't mistakenly wind up in a student's hands. Trump posted on Twitter.
The shooting has sparked a movement across high schools in the USA with Florida survivors spearheading the push for gun control.
"I will be strongly pushing Comprehensive Background Checks with an emphasis on Mental Health", Trump tweeted Thursday.
"Their goal is to eliminate the Second Amendment and our firearms freedoms so they can eradicate all individual freedoms", LaPierre said, speaking at the annual Conservative Political Action Conference to an audience that typically bristles at the notion of restricting Second Amendment rights.
He concluded his speech to a gathering of conservative leaders with the NRA catchphrase: "To stop a bad guy with a gun, it takes a good guy with a gun". "We need to arm our teachers with more money in their pocket". The meeting took place a week after the mass tragedy at Marjory Stoneman Douglas High School that left 17 people dead and 14 others injured. He has floated the idea of arming teachers as a possible deterrent.
Republican Senator Marco Rubio, who has long opposed gun control measures, and a teacher who had protected more than 60 people in her classroom in the Florida massacre, questioned the notion of armed teachers during a CNN discussion.
Cruz's attacked lasted for only minutes before he slipped out of the school as his former classmates evacuated.
Investigators said the assault was carried out by 19-year-old former Stoneman Douglas student Nikolas Cruz, who purchased an AR-15-style assault weapon almost a year ago.
While Trump didn't appear to use the note much, if at all, during the meeting, the fact that he would need a supplementary device to do not forget to show basic human decency and sympathy to survivors of one of the worst school shootings in the nation's history is ridiculous. There are many ideas that other people have, and we're going to pick out the strongest ideas, the most important ideas, the ideas that are going to work, and we're going to get them done.
The presidents comments came after he spent the morning trying to clarify his view on arming teachers, a proposal he floated at Wednesdays session with survivors, and which has met with stiff opposition. "If I have to, I'm gonna try and perhaps override the states". "Am I supposed to strap it (the gun) to my leg or put it in my desk?"
'What I said was to look at the possibility of giving "concealed guns to gun adept teachers with military or special training experience - only the best". I don't want to tell my son 'you're going to have to participate in an active shooter drill. "We must keep our children safe!"
When asked by radio host Hugh Hewitt about arming teachers, the US education secretary, Betsy DeVos, said states "clearly have the opportunity and the option to do that".
"You see these movies, they're so violent and yet, a kid is able to see the movie if sex isn't involved", he went on.
