Law Firm Defending Trump Seeks to Withdraw From a Long-Running Case

A law firm that has long defended Donald J. Trump’s campaign and businesses from employment lawsuits has abruptly asked to withdraw from a yearslong case over what it calls an “irreparable breakdown in the attorney-client relationship.”

The firm — LaRocca, Hornik, Greenberg, Rosen, Kittridge, Carlin and McPartland — has represented Mr. Trump’s political operation in numerous suits dating to his first presidential run, helping secure several settlements and dismissals and billing nearly $3 million in the process.

But late on Friday, it asked a federal magistrate judge to allow it to withdraw from a suit filed by a former campaign surrogate, A.J. Delgado, who says she was sidelined by the campaign in 2016 after revealing she was pregnant. The timing of the motion was notable, just two days after the same federal court had ordered the campaign to turn over in discovery all complaints of sexual harassment and gender or pregnancy discrimination from the 2016 and 2020 campaigns — materials that the defendants have long resisted handing over.

In the request, filed in federal court in Manhattan, the lead lawyer, Jared Blumetti, did not provide any details about the dispute, asking permission to “explain” the matter privately with the judge. Mr. Blumetti did not respond to a request for comment.

The apparent rupture with a long-trusted firm comes at a busy time, legally speaking, for the former president.
