I missed that. What happened?
After the intro, Cruz's speech moved into a story of the 9-year-old child of one of the Dallas police officers (Michael Smith) recently killed by the sniper. He talked about the child's last goodbye with her father, and then spoke about her father's bravery and his commitment to America and it's freedoms.
And, then he refused to endorse Trump...and was booed off the stage.
