Texas Gun Control and Safety Advocates Push for Change Amidst Tragic Shootings.

The Uvalde school shooter wrote "LOL" in the blood of his victims on a classroom whiteboard, according to Texas House Rep. Joe Moody. The revelation came during a hearing for a bill that would raise the age to purchase certain semiautomatic rifles from 18 to 21. Families of the victims pleaded with Texas legislators to pass the bill, which has faced opposition from Republicans, including Gov. Greg Abbott. The bill exempts police, members of the military, or anyone honorably discharged from the military. The hearing continued into the early hours of Wednesday morning.
