The sheriff in Broward County, Florida, where 17 high schoolers were killed at Marjory Stoneman Douglas High School, has said deputies will be allowed to carry rifles on school grounds, the Associated Press reports.

The backdrop: At a listening session at the White House on Wednesday, President Trump advocated for armed personnel to be in schools as a way to prevent school shootings.

Per the AP, the resource officer at the high school "was carrying a weapon when the shooting happened last week but did not discharge his firearm."

When the rifles are not being used, they will "be locked in a patrol car ... until the agency secures gun locks and lockers."
