Cruz said he introduced legislation hat would have allocated $1.3 billion for schools to protect their perimeters.

“Again, the Democrats blocked a vote on it,” he said. “And I got to say this is frustrating here. This mass murderer came in through an unlocked door in the back of the school. The exact same way the mass murderer came in to the school in Santa Fe just outside of Houston.”

Cruz said he met with the family members of the victims after that shooting, and they agreed with him that multiple entry and exit points leave schools vulnerable.

“One of the things that earn agreed is don’t have all of these unlocked back doors,” he said. “Have one door into and out of the school and have that one door, armed police officers at that door. If that had happened, if those federal grants had gone to this school, when that psychopath arrived, the armed police officers could have taken him out and we would have 19 children and two teachers still alive.”
