Julián Castro, the former housing secretary whose progressive presidential candidacy did not make significant inroads with Democratic voters but earned plaudits from the party’s left wing, has endorsed Senator Elizabeth Warren of Massachusetts, offering a possible lift for her candidacy less than one month before the Iowa caucuses.

Mr. Castro announced his endorsement on Monday morning, just days after he ended his own bid for the White House. In a statement, Mr. Castro cast Ms. Warren as the logical extension of his campaign’s social-justice-driven message, which seeks to correct inequities through targeted policy proposals. He will campaign with Ms. Warren this week, joining her Tuesday night at a rally at Kings Theatre in Brooklyn.

“There’s one candidate I see who is unafraid to fight like hell to make sure that America’s promise will be there for everyone,” Mr. Castro said in a video announcement released on Twitter. Ms. Warren, he said, “will make sure that no matter where you live in America — or where your family came from in the world, you have a path to opportunity, too.”

As noted in the article Castro did not garner a great deal of excitement during his campaign, but his endorsement is still noteworthy and may help to give Warren’s campaign a boost that it sorely needs right now.
