11-year-old Uvalde student tells lawmakers what she had to do to survive

It was an emotional day of testimony at a House hearing on gun violence as 11-year-old Miah Cerrillo recounted her harrowing experience during the Uvalde school shooting. The fourth grader told members of Congress in a pre-recorded video that she saw her teacher and friends murdered. She said she smeared blood all over herself and kept quiet so the gunman wouldn't notice her.
