Video of a Donald Trump town hall-style rally in New Hampshire shows the GOP presidential candidate responding to a question about immigration by accusing the questioner of being a plant from the Bernie Sanders campaign. The question, voiced from a woman who identified herself as being from California, questioned Trump’s stance on immigration, asserting that immigrants "do work that no one else wants to do and for a lot less." It’s hard to hear the entire question in the video because of the audio quality.

“Who told you to be here? Bernie?,” he asks rhetorically. “No, no, this is a Bernie plant. This is a Bernie plant.”

According to Fox News Latino, that’s when another audience member -- not the woman whose question was talked over -- shouted that immigrants (or illegal immigrants; it’s unclear) are the “backbone of our country.” Video the shows Trump responding to those shouts with a sharp response.

“Oh, illegal immigrants are the backbone of our country? I don’t think so, darling,” Trump says. “I don’t think so. I don’t think so. No, I don’t think so. They’re not the backbone [....] You know what the backbone of our country? [...] People that came here to this country legally, and they worked their ass off, and they made this country great.”

Trump’s message has immigration message has resonated with New Hampshire voters, and put him 20 points ahead of his rivals in ahead of the state’s Feb. 9 primary election.
