Rafael Cruz is headed to the Republican convention to vote for his son, the vanquished former GOP presidential candidate Sen. Ted Cruz.

The preacher will be one of 155 Texas delegates to July's Republican National Convention in Cleveland.

"He is a delegate," Butch Davis, chairman of the party's National Nominations Committee, told The Dallas Morning News.

The elder Cruz is on the list of at-large delegates voted on by the National Nominations Committee, which selects at-large delegates who are then routinely approved by Texas Republicans at the state GOP convention, which meets this weekend. Rafael Cruz, not surprisingly, told members of the National Nominations Committee that he will vote for his son at the GOP's nominating convention in July, according to the report.

Cruz won 24 delegates of the at-large pool, while Trump won 17. Each of Texas' 36 congressional districts also picks and assigns three delegates to the to candidates. Cruz, who won the state, will get the most delegates, followed by Trump. Florida Sen. Marco Rubio will pick up delegates too.
