Bolduan cut off her guest and responded, “I don’t know if you want to go as far as — I mean, let’s not — I just did an entire segment about civility here. I don’t know if you want to call Stephen Miller a white nationalist.”

“Well, it’s not an uncivil thing. I would argue that it’s a fact,” Leopold countered.
