New York City Mayor Eric Adams is seriously considering endorsing Darializa Avila Chevalier, a Democratic Socialist America-backed candidate challenging incumbent Representative Adriano Espaillat in an Upper Manhattan House primary, according to reports.

The potential endorsement would mark a significant shift for Adams, who had previously pledged to support Espaillat in his reelection bid. Espaillat currently represents New York's 13th Congressional District, which covers parts of Upper Manhattan including Harlem and Washington Heights.

Avila Chevalier is running as a democratic socialist candidate, aligning herself with the Democratic Socialists of America organization. Her candidacy represents a progressive challenge to the incumbent congressman from the left.

The primary race highlights ongoing tensions within the Democratic Party between establishment figures and progressive activists. Adams' potential endorsement decision comes as he navigates his own political positioning within the party.

Neither Adams' office nor representatives for Espaillat or Avila Chevalier immediately responded to requests for comment about the reported endorsement consideration. The primary election date has not yet been specified in available reporting.
