The residence of Sen. Ted Cruz, R-Texas, received a visit from a fleet of 52 yellow school buses in a mobile procession protesting gun violence. Gun control advocacy organization Change the Ref led the mile-long convoy to Cruz's office, stopping first at Cruz's Houston home in the protest dubbed, “The NRA Children’s Museum.” The buses contained 4,368 empty seats, according to a press release from Change the Ref, a reference to the number of children who were killed by gun violence in 2020. Supporters of Change the Ref said they want Cruz to implement universal background check legislation for those who want to buy a gun, the release states. Some of the buses featured an exhibit of artifacts, photos, videos, audio recordings, and personal memories of these children who have lost their lives to guns.
