In the aftermath of the elementary school massacre in Uvalde, Texas, the Miami Heat used a pre-game moment to urge fans to contact U.S. Sens. Marco Rubio and Rick Scott, both Florida Republicans, “demanding their support for common sense gun laws” — and telling them they can “make change at the ballot box.” Rubio, who is up for re-election this fall, didn’t like it. He took to Twitter on Thursday, lambasting the NBA for “politicizing a horrific tragedy in America.”
