Watch: Mother of slain Florida student screams at Trump live on camera -- and CNN's Brooke Baldwin falls apart

Mother Lori Alhadeff lost her daughter Alyssa Wednesday after Nikolas Cruz, a 19-year-old man, killed 17 students at the Marjory Stoneman Douglas High School in Parkland, Florida. In an interview with CNN Thursday she screamed into the camera demanding President Donald Trump do something.

"How? How do we allow a gunman to come into our children's school?" Alhadeff asked. "How do they get through security? What security is there? There's no metal detectors. The gunman, a crazy person, just walks right into the school, knocks on the window of my child's door and starts shooting, shooting her and killing her!"

She then turned her anger to the president.

"President Trump, you say what can you do?" she asked, responding to Trump's statement earlier. "You can stop the guns from getting into these children's hands! Put metal detectors at every entrance to the schools. What can you do? You can do a lot! This is not fair to our families and our children go to school and have to get killed! I just spent the last two hours putting the burial arrangements for my daughters funeral, who is 14! Fourteen! President Trump, please do something! Do something. action! We need it now! These kids need now!"

The cameras cut back to Baldwin, who is in Parkland meeting with families and covering the tragedy. She cast her eyes down and held up her hand, her voice cracking.

"Sorry, Gary, thank you," Baldwin said before she paused again. "I'm sorry. It's just -- Congressman [Ted] Deutch, help me out, of Florida here. Just hearing that mother, I'm sorry. It got me."

Deutch talked to Baldwin about things that should be done but Baldwin hammered him on what he actually intends to do. Like many Democrats, however, Deutch doesn't have any power in Congress to go up against the gun lobby.
