CNN anchor Don Lemon told network contributor Matt Lewis to "shut up" late Tuesday during an explosive debate over what constitutes a "mob" in light of Sen. Ted Cruz Rafael (Ted) Edward CruzCruz blocks amended resolution honoring Ginsburg over language about her dying wish Trump argues full Supreme Court needed to settle potential election disputes Press: Notorious RBG vs Notorious GOP MORE (R-Texas) and his wife being chased out of a restaurant.

The back-and-forth came hours after anchor Brooke Baldwin tangled with Lewis and fellow CNN contributor Mary Katherine Ham over whether protesters should be labeled as a mob, with Baldwin telling both she wanted to "move past the M-word" because it is "part of the weaponization of what’s happening now on the right."

Lewis was invited on Lemon's show, "CNN Tonight," to continue the conversation, where the conservative Daily Beast columnist made the point that the Tea Party "didn't hound people out of restaurants" as was the case with Cruz last month or Homeland Security Secretary Kirstjen Nielsen Kirstjen Michele NielsenMore than million in DHS contracts awarded to firm of acting secretary's wife: report DHS IG won't investigate after watchdog said Wolf, Cuccinelli appointments violated law Appeals court sides with Trump over drawdown of immigrant protections MORE over the summer.

“The Tea Party did hound people. The Tea Party people hounded me when I went out to cover them!” Lemon shot back. “And do you know what I said? It was their right to do it because they’re Americans!”

“Don, if they started following you around a restaurant and running you out of places,” Lewis replied.

“But that doesn’t mean that people don’t get to object,” Lemon interrupted. “That’s your right as an American to object. It’s covered in the First Amendment. It’s like the first one!”

After some extended verbal volleying over the proper definition of a mob, Lemon lost his patience.

"Will you let me finish? Matt, please! Let me finish," Lemon exclaimed.

"Bring it on. Mind if I have a drink?" Lewis asked.

"You can do whatever you want. You can leave the show if you want," Lemon replied.

"I’m not going to do that," Lewis said.

"Shut up and let me do it," Lemon said.

"Thank you very much," the anchor continued. "In the Constitution, you can protest whenever and wherever you want. It doesn’t tell you that you can’t do it in a restaurant, that you can’t do it on a football field. It doesn’t tell you that you can’t do it on a cable news you can do it wherever you want."

"To call people mobs because they are exercising their constitutional right is just beyond the pale," Lemon concluded before going to break.
