Texas Gov. Greg Abbott is receiving a warm welcome from the entire delegation, led by Texans waving their white cowboy hats.
Watch Abbott's remarks in the player above.
"I can tell you America needs a president that will secure our border," says Abbott, governor of the state with the largest section of the U.S.-Mexican border.
Abbott criticized the Biden administration for objecting to his administration's effort to secure more of its section of the border, "to take back our land and wire it shut."
Abbott's remarks prompted thousands in Fiserv Forum to chant, "Send them back, send them back."
