Polls have shown Cruz and O'Rourke in a tight race in deep-red Texas, and the Hispanic vote could be key to November's results. 

Cruz is getting support from 45 percent of likely Hispanic voters, 9 percent shy of the 54 percent who support O'Rourke, according to a Quinnipiac University poll released this week. 

Julián Castro, a former mayor of San Antonio, sits on the board of directors for Voto Latino, a nonprofit that encourages more political activity among Hispanics.

He has also said that he is considering running for president in 2020, telling CSPAN in May that he would make a decision on whether to seek the nomination after the midterms.

His brother, Joaquin, has served in the House since 2013 as a representative for Texas's 20th Congressional District, which includes part of San Antonio.
