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

Somehow I don’t think it’s about money.

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.
