The Latest: Ban proposed on young buying assault rifles
WASHINGTON (AP) — The Latest on President Donald Trump  guns and school violence (all times local):
President  Donald Trump  endorsed barring those under 21 from buying semi-automatic weapons — a move that puts  him  in direct opposition with the National Rifle Association.
 His  comments Thursday came amid a public reckoning over school gun violence after last week's Florida school massacre. NRA officials have opposed the idea  but  Trump  says they'll get on board.
 President Donald Trump  says drills that teach students how to respond if an active shooter ever enters the premises "are a very negative thing."
 Trump  says  he  wouldn't want to tell  his  son that  he  has to go through an active-shooter drill. The youngest of  Trump 's five children  11-year-old Barron  attends a private school in Potomac  Maryland.
 The president  says  he 'd prefer what  he  called a "hardened school" over active-shooter drills.  Trump  has said making schools safer will be a top priority for the administration.  He  has floated the idea of arming teachers as a possible deterrent.
 Trump  spoke as  he  opened a school-safety discussion with state and local officials at the White House in response to the fatal shooting of 17 people at a Florida high school last week.
 President Donald Trump  says  he 's speaking with members of Congress about making schools safer following last week's deadly shooting at a Florida high school.

 Trump  says  the group  will also discuss opening mental institutions.
Thursday's session follows one on Wednesday in which  the president  heard emotional pleas from students and parents affected by the fatal shooting of 17 people at a Parkland  Florida  high school.
Speaking at the Conservative Political Action Conference  Pence recounted President Donald Trump's calls for strengthening the federal background check system for purchasing firearms and for regulating bump-stocks like those used in last year's Las Vegas massacre.
 President Donald Trump  is offering a full-throated backing of the National Rifle Association.
