Sen. Bernie Sanders’s (I-Vt.) White House campaign on Thursday named activist Nick Salazar its Iowa state co-chairman as it works to gin up support among Hispanics.

The campaign said in a statement that Salazar, the Iowa state director for the League of United Latin American Citizens (LULAC), will join Rep. Alexandria Ocasio-Cortez (D-N.Y.) at a rally in Coralville on Saturday.

“To win Iowa and build a movement we are bringing together a diverse group of leaders, along with millions of people, who are prepared to fight for justice, and I am ready to be a part of that fight as campaign co-chair here in Iowa.”

Salazar joins Linn County Supervisor Stacey Walker as one of the Sanders campaign’s Iowa campaign co-chairs.

He was unanimously elected in May as LULAC Iowa’s state director, becoming the youngest person to ever serve in that role.

The Sanders campaign has put a premium on boosting its appeal to Hispanic voters, a key Democratic constituency. It unveiled a sweeping immigration plan Thursday that, among other things, would undo all of President Trump’s executive actions on immigration and put a moratorium on deportations and raids by Immigration and Customs Enforcement. 

“They’re enormously important,” Sanders told Politico last month. “We are seeing the Latino population growing very significantly. We’re seeing young people getting involved in the political process in a very important way. The challenge that we face is that, historically, voter turnout in the Latino community is not very high. So we are doing everything we can in a variety of ways to organize.” 

Iowa holds the first statewide vote in the primary cycle. Polls show Sanders consistently in the top tier in the state’s caucus, along with former Vice President Joe Biden, Sen. Elizabeth Warren (D-Mass.) and South Bend, Ind., Mayor Pete Buttigieg.
