Roland Martin tells former Bush speechwriter to not quote Martin Luther King. It quickly gets testy.

An MSNBC panelist apparently made a grievous error by invoking a famous phrase from Dr. Martin Luther King Jr.'s "I Have a Dream" speech Sunday — at least fellow panelist Roland Martin, host of TV One, seemed to think so.

The topic on “Live with Alex Witt” was White House intern diversity, specifically a comparison between those under President Donald Trump and those under former President Barack Obama.

And it didn't take long for panelist Jennifer Grossman — who wrote speeches for former President George W. Bush — to utter the magic words.

“My thoughts are largely that the most important thing is the content of our character and what’s in our heads and our ideas and our thought, not the color of our skin. So whether or not you have racial diversity in that intern class, I would argue probably you have a lot more diversity in terms of political viewpoints because ... President Trump’s election has really stirred things up," Grossman noted, adding that a broad spectrum of interns who lean right are likely represented.

She added that she would be “a little concerned about creating intern classes where everybody looks different but thinks the same."

Martin attempted to interject several times, seemingly anxious to push back on Grossman using "content of our character," and then he made his pronouncement: “Jennifer, do me a favor, please don’t quote Dr. King, the bottom of his March on Washington 'I Have a Dream' speech ..."

How testy did things get?

Grossman shot back immediately.

“I will quote him every single ...” Grossman told Martin as she waved her finger and the pair began talking over each other. “No, no, no. And this kind of thing does not work. Do you want to have more of a debate on race?”

"Allow me to finish!" Martin pleaded several times.

“Your kind of politically correct bullying of people on racism is not going to work," Grossman continued, her tone growing sharper. "So I will quote Dr. Martin Luther King every single day. And you won’t stop me.”

Martin then explained that people "love" to quote the bottom of King's speech but not the top of it where he addressed issues such as police brutality and the right to vote.
