Beto O’Rourke is defending the F-bomb he dropped Wednesday night while confronting a heckler who he said was laughing during his remarks about the Uvalde mass shooting that killed 19 elementary school students and two teachers. The incident occurred during a rally in Mineral Wells as O’Rourke began talking about the need to curb mass shootings like the one that happened May 24 at Robb Elementary School. A man in the crowd could be seen and heard laughing as O’Rourke talked about Uvalde, prompting the Democratic nominee for governor to respond with an expletive.
