SAN ANTONIO — Sen. Elizabeth Warren endorsed congressional hopeful Jessica Cisneros in San Antonio Tuesday.
The move comes as the nation's attention turns toward the hotly-contested Democratic primary in Texas's 28th congressional district. Political pundits say the results may hint at the democratic party's future.
"This is an opportunity to get a progressive voice at the table when decisions are made," the former presidential candidate told reporters after the rally.
Warren did not mention incumbent Democrat Rep. Henry Cuellar during her speech. Instead, she told the crowd that some core democratic values are at risk.
Cisneros, however, spent considerable time attacking Cuellar's voting record.
"He's voted with Donald Trump 70 percent of the time," she said. "He was anti-choice... he was anti-labor."
Warren is the latest, well-known progressive to visit San Antonio. Cuellar accused Cisneros of attracting "far-left" celebrities when Rep. Alexandria Ocasio-Cortez (D-New York) visited last weekend.
Senator Warren will also appear with Greg Casar at a meet and greet in east Austin Wednesday.
Casar is on the ballot for Texas's 35th Congressional District, stretching from Austin down to San Antonio. Congressman Lloyd Doggett currently represents the district but said he would run for the newly created 37th District.
The Texas primary election will be held on March 1. Early voting this week goes until Friday, February 25.
