Uvalde school shooter's cousin arrested

San Antonio police said the 17-year-old cousin of the man who opened fire at Robb Elementary School in Uvalde, Texas has been arrested. Court documents state his mother called police and said her son had threatened a mass shooting at a school and “planned to do the same thing” as his cousin. Brett Cross, whose son was killed in the Uvalde attack, joined LiveNOW from FOX's Josh Breslow to discuss the arrest.
