U.S. Magistrate Judge Katharine H. Parker of the Southern District of New York on Thursday ordered the law firm seeking to withdraw from representing former President Donald Trump’s presidential campaign in a pregnancy discrimination lawsuit to provide more information about the alleged deterioration in its relationship with its client.

Parker wrote that the declaration accompanying the motion to withdraw, which was filed by LaRocca Hornik partner Jared Blumetti on Friday, was “insufficient to grant withdrawal at this time.”
