U.S. Sen. Ted Cruz, a Republican from Texas, walked off on a British journalist after he was pressed about reforming gun laws, and asked why mass shootings happen so frequently in America.
The exchange happened two days after a gunman killed 19 children and two adults at Robb Elementary School in Uvalde, Texas, making it the second-deadliest mass shooting at an elementary, middle or high school in U.S. history. Cruz was attending a vigil for the victims.
