Wednesday on MSNBC’s “Morning Joe,” Sen. Chris Murphy (D-CT) responded to his colleagues in the Senate and others accusing him of “politicizing” the tragic mass shooting at an elementary school in Uvalde, TX, which has reportedly left 19 children dead. Murphy, who in an interview the night before pushed for gun control in the wake of the shooting, pushed back against the notion that he was “supposed to shut up and not talk about changing laws” following shootings. He argued that not politicizing the shootings was “a fiction created by the gun industry.”
