EAST LAS VEGAS — Sen. Elizabeth Warren’s call to eliminate private immigration prisons drew raucous support Tuesday evening during a town hall in Las Vegas.

With 2020 Democratic presidential candidates campaigning across the country, the Massachusetts senator was the first of at least four making stops in Clark County over the July Fourth holiday.

A diverse crowd her campaign estimated at 600 came out to see Warren, many supporters with signs that reflect the diversity of the neighborhood. There were “Warren has a plan” signs printed in Spanish throughout the audience.

She covered a variety of economic and foreign policy topics, touting her proposed surtax on the investment assets of individuals in excess of $50 million, and in responding to a question highlighting support for ending endless war authorizations.

But it was immigration policy where the focus landed Tuesday, owed in part to the reports on conditions of migrants held in U.S. custody and in part to the audience itself.
