Vice President JD Vance received a mixed reception during an event put on by the National League of Cities in Washington, DC Monday. The vice president was heckled several times during his remarks about illegal immigration and the rising cost of housing in the United States. "When we talk about housing and why costs are so high, we don't talk enough about demand," Vance said. "And one of the drivers of increased housing demand, we know, is that we've got a lot of people over the last four years who have come into the country illegally, and that's something we have to work on if we want to meaningfully reduce the cost of housing." he said. Vance was heckled when he broadened his argument, saying countries that have experienced a big influx of migrants have also seen a major rise in the cost of buying a home. "You go across the world and you see a very consistent relationship between a massive increase in immigration and a massive increase in housing prices." It wasn't clear from the recording of Vance's remarks who the heckler was, or exactly what the heckler was saying, but Vance responded directly. "I see one of our nice representatives out here wants to actually, I guess, continue to flood the country with illegal immigrants, making your communities and citizens unaffordable." Vance was loudly cheered by audience members when he spoke about the administration's rationale for border security. "We want your communities to be safer," he said. "We want them to be more affordable. We want there to be less drugs in our country. And we want your citizens to be able to live the American dream." However, he was heckled again moments later. "Come and tell us when you disagree with our policies and we'll have a conversation about it. Maybe don't shout it in front of 2000 people. I can't even hear what you're saying, sir," Vance said. "While we have immigration laws on the books, we will enforce them and we expect our local municipalities to help us," he said. "We've got to have everybody respecting the law. And that is going to be one of the major policy focuses, of course, of the Trump administration, and it already has been," he said.
