In a panel discussion on CNN, Pierson said that Trump's nebulous immigration policy hasn't shifted.
"He hasn't changed his position on immigration," she said. "He's changed the words that he is saying."
"That would be a change," another panelist pointed out through laughter offscreen.
Pierson, undaunted, plowed on.
"There's not a different message," she argued. "He's using different words to give that message."
Trump himself seemed unsure of his position on immigration reform, turning to the audience of his Fox News town hall on Wednesday night to conduct an impromptu poll on the matter instead of discussing specific details of his policy.
