U.S. Rep. Colin Allred, D-Dallas, will speak from the main stage of the Democratic National Convention on Thursday to express his support for Democratic presidential nominee Vice President Kamala Harris, his campaign said.

Allred is challenging U.S. Sen. Ted Cruz, R-Texas, this year in one of the Senate Democrats’ top flip targets this year. He has so far run his race largely independent of Democrats outside the state, focusing on Texas issues rather than yoking his candidacy to the presidential ticket. During an address to the Texas delegation on Thursday morning, Allred leaned heavily into attacking Cruz without mentioning Harris.

"I want to both run for this office the way I plan on serving in it, which is that I'm focused on Texas," Allred said in an interview Thursday morning. “We have a very singular choice, which is who's going to serve us for the next six years. It's going to be until 2030, past the … term of the next president.”

Allred will share the stage with other House Democrats in competitive Senate races, including Michigan’s Elissa Slotkin and Arizona’s Ruben Gallego. Michigan and Arizona are both considered more competitive than Texas. He will speak shortly before Harris takes the stage to close out the convention.
