MSNBC's Chris Matthews accuses the Marco Rubio campaign of putting plants in the CNN Republican debate audience to "squeal" and clap enthusiastically "every single time" Rubio said anything. Matthews called it the "most unnatural, phony thing in the world."



"I hope people when they watch this know this was all choreographed. It was all part of a P.R. operation," Matthews said Thursday night.



"It was that squealer out in the audience that was clearly [Rubio media consultant] Todd Harris and the rest of the Rubio people hired to put her out there, a couple of them, three or four of them, squealing at the top of their lungs every single time that Rubio said anything. It was the most unnatural, phony thing in the world. And I hope people when they watch this know this was all choreographed. It was all part of a P.R. operation," Matthews said on MSNBC.



Trump often accuses the audience of being stacked with lobbyists and friends of the establishment.
