Hundreds of people cheered the husband of Kentucky clerk Kim Davis during a rally of Christian conservatives outside the Tennessee Capitol.

Thursday's celebration of Constitution Day also brought Rafael Cruz, the father of U.S. Sen. Ted Cruz, a presidential candidate. Cruz didn't directly ask the crowd to vote for his son but did say the country needs to elect a constitutional conservative who will end what he called the religious persecution of Christians.

Cruz acknowledged Joe Davis, the husband of the Rowan County, Kentucky, clerk who was jailed for five days after defying a federal judge's order to process same-sex marriage licenses. Cruz said what happened to Kim Davis was tyranny.

Joe Davis asked the crowd to pray for him and his wife.
