BALDWIN: Welcome back. I'm Brooke Baldwin. To now a very public breakdown of civility in a place literally built for civilized debate. It happened inside the Texas capitol on Memorial Day, the final day of the state legislative session. Basically, a schoolyard shoving match broke out among several state lawmakers right there on the house floor. See for yourself? In the backdrop, you have hundreds of protesters rallying against this new law that bans sanctuary cities in Texas. Republican Matt Rinaldi says he saw signs that declare some demonstrators were undocumented, so he stood up and told fellow lawmakers that he called ICE, he called immigration officials. And Rinaldi says that is when one lawmaker assaulted him, while another threatened him, prompting Rinaldi to issue a warning he was willing to shoot his gun in self-defense. The accused lawmakers deny any assault or threats. We reached out to Rinaldi, I should point out, not once, not twice, three times, to speak with him, but so far got no response. Who we did get a call back from, and I'm grateful to both --
