President Trump on Thursday reacted to the deadly high school shooting in Florida that killed 17 people, tweeting: "So many signs that the Florida shooter was mentally disturbed, even expelled from school for bad and erratic behavior. Neighbors and classmates knew he was a big problem. Must always report such instances to authorities, again and again!"
The tweet about the 19-year-old suspect, identified by police as Nikolas Cruz, was written as a "reply" to Trump's tweet from Tuesday about congressional negotiations on the Deferred Action for Childhood Arrivals program, although there was no obvious correlation:
Cruz, who was adopted, had apparently been living with a friend's family after the death of his mother three months ago, from the flu and pneumonia, CNN reports. He had also reportedly made social media posts like "I [wanna] shoot people with my AR-15" and had legally bought the firearm used in the attack after passing the background check within the past year.
