Thursday on CNN’s “Newsroom with Brooke Baldwin,” while discussing Republican presidential frontrunner Donald Trump’s complaints about the Colorado caucus system, Sen. Ted Cruz (R-TX) supporter and conservative radio host Steve Deace lost his patience with Donald Trump supporter, CNN’s Kayleigh McEnany.

Partial transcript as follows:

MCENANY: Donald Trump tried to enfranchise people, give them for a greater voice. In contrast to Ted Cruz, who willingly stood against the people of Colorado, who willingly has been playing this delegate game to try to take the people’s will out of the equation. That’s what the Washington establishment does. They throw out the popular vote. They throw out the will of the people, and they put their own personal aspirations first. That’s what Ted Cruz has been doing the last few weeks. That’s why he is losing.

DEACE: I’d like to respond to that.

BALDWIN: Please do.

DEACE: I’d like to respond to that. Kayleigh, I don’t know you. Seriously, do you have any integrity at all? I just have to know. I mean, is it that important to be on national television?

BALDWIN: Oh, ouch. Come on now, Steve. Let’s be professional.

DEACE: You darn well know 65,000 people — I am keeping it professional. She’s the one lying. 65,000 people voted in Colorado, at this thing called a caucus, called an election. There has been no voterless elections. Every delegate has been elected, including the delegates unbound that Donald Trump got in Pennsylvania the other night. This is the biggest lie, and the biggest scam, from a guy that’s lied repeatedly throughout this entire campaign, whose campaign is built on a lie. I’m Mr. Anti-Establishment when I wrote all these guys checks. Yesterday, Mr. Trump was defending [Sen.] Mitch McConnell (R-KY). Today, he’s taking hosannas from John Boehner. This whole thing is a scam. And there are millions of Americans that watch people like you, sit here and go on these shows, and Scottie Hughes, and the rest of this cabal of motley crew of advisers, who just sit here and fete this guy, and lie about him and for him every single day, and millions of Americans are freaking just sick of it. Stop lying! There wasn’t a voterless election in Colorado! You’re a liar! Stop lying, please.

BALDWIN: Wow, wow. Hang on a second. Hang on a second. No ones comes on my show and calls anyone a liar. With all due respect. The deal in Colorado is yes, you are correct. People vote, I had somebody one who wanted to become a delegate –.

DEACE: Then if I’m correct, she lied! If I’m correct, she lied, Brooke!
