Tempers flare on CNN.

CNN’s “Newsroom” Host Brooke Baldwin sat by and allowed a Democrat to racially attack a Black Republican and tell him to “Shut up!” on Monday.

Earlier in the day, another CNN host demanded a Republican apologize for telling someone who kept interrupting him the same thing.

Discussing last weekend’s violence in Charlottesville, Va., on Baldwin’s show, former aide to President Bill Clinton Keith Boykin launched a racial assault on Republican Paris Dennard - saying he was "ashamed" of Dennard "as an African-American person" for refusing to denounce Trump for not doing enough to denounce racism.

“Keith, I don’t need you to try to pull my Black card. I am well aware of my Blackness and I don’t need you to classify me as being one. I understand what racism is,” Dennard said - before being cut off by Boykin, who disagreed that Dennard knew racism.

That’s when things got loud and heated.

Boykin tried to talk over Dennard, who repeatedly had to shout, “Keith, Let me finish!”

Dennard described the racism he experienced for being a Black Republican. And, when Boykin mocked him, Dennard said that his family had, in fact, been victimized by the KKK:

“Keith, don’t go there. Do not go there. I know what it means to be a Black man in this country. I experience racism on a regular basis by being a Trump supporter and by being a proud American who happens to be Republican. I get racist…(Boykin interrupts) “Keith, let me finish! I get racist comments about my family, about my mother, about my girlfriend, about my character – every single day, mostly coming from Black people.” …. “My family is from Georgia – Keith, let me finish! – my family is from Georgia, we have members of our family that went missing because of the KKK taking them up. “So, don’t come to me and tell me about what it means to be a black person in this country. “Keith, let me finish! No, I will not calm down, because I will not be attacked by you about my Blackness because I happen to be a Republican and I listen to our president.”

“Get your guest under control,” Dennard urged Baldwin, adding, “I will not come on this show and be disrespected.”

Boykin then cried out, “Paris, shut up , please! For God’s sake!”

“So, are you going to let him tell me to shut up,” Dennard asked the CNN host. “Don’t tell me to shut up on this show! This is preposterous!” Dennard told Boykin.

Balwin never asked Boykin to apologize.

But, earlier on Monday, CNN host Chris Cuomo demanded Ken Cuccinelli apologize for telling a Democrat to shut up when she kept interrupting him and the CNN host did nothing to help Cuccinelli finish his sentences.
