(CNN) President Donald Trump continued to criticize the armed school resource officer in Parkland, Florida, who stayed outside of the school during the shooting, saying during a White House news conference conference that Scot Peterson "doesn't love the children, probably doesn't know the children."

The comments tie into Trump's push to arm some educators, including teachers, to deter school shootings. Trump has argued that officers outside the school don't care about the students the same way teachers do.
