'How many have to be killed?:' Uvalde speakers testify in emotional House hearing

"My question to the leaders of this country is how many children have to be murdered before they are willing to ban the chosen weapon of these school shooters?" Texas State Senator Roland Gutierrez asked.

Earlier this year, the U.S. Congress passed the first major federal gun reform in three decades, a bipartisan bill that included $750 million to help states implement red flag laws. It came together just weeks after two teachers and 19 elementary school students were killed in Uvalde, Texas, and 10 people were shot to death at a supermarket in Buffalo, New York.
