After the shooting happened, Trump tweeted:
"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!"
Her response at the time at a press conference:
"We did, time and time again. Since he was in middle school, it was no surprise to anyone who knew him to hear that he was the shooter. Those talking about how we should have not ostracized him, you didn't know this kid, OK? We did. We know that they are claiming mental health issues, and I am not a psychologist, but we need to pay attention to the fact that this was not just a mental health issue. He would not have harmed that many students with a knife."
Sounds like she needs to direct her impotent rage at the FBI for not acting on it rather than the President and NRA, guns or not. They were watching the Pulse nightclub shooter for some time and didn't do anything there either.
