Arizona Sheriff Joe Arpaio took the stage as the last speaker, but he was the one the crowd cheered for the most.
Arpaio is being sued by the U.S. Department of Justice, accusing of using racial profiling on immigration patrols.
He said that's not the case and criticized President Barack Obama's orders to stop deportation cases for some illegal immigrants who came to the U.S. as children.
"People play politics all the time, but I think he's played a little too far on the immigration situation," Arpaio said.
Other speakers talked about the election, health care, cutting spending, and supporting the definition of marriage as between a man and a woman.
