Joe Biden addressed the nation from the White House late Tuesday following a mass shooting at Robb Elementary School in Uvalde, Texas. At least 21 people have died at the hands of the shooter, identified as 18-year-old Salvador Ramos, at the time of this writing, including 18 children and one teacher. In addition, a Border Patrol agent was shot responding to the incident. He was just trying to help out; there was no immigration nexus to the matter. Ramos allegedly shot his grandmother earlier in the day, drove to the school, and began shooting.
