Roberta A. Kaplan, the celebrated lawyer who took on former President Donald J. Trump, and helped win marriage equality for gay Americans, is stepping down from the law firm she founded after clashing with her partners over her treatment of colleagues. Ms. Kaplan, a hard-charging civil rights lawyer, announced that she was leaving the firm, Kaplan Hecker & Fink, which she formed in 2017, to start a new one. Her departure followed months of internal frustration over Ms. Kaplan’s conduct toward other lawyers, according to people familiar with the matter. Those concerns led her colleagues to remove her from the firm’s management committee and precipitated her departure. Ms. Kaplan’s former firm will be renamed Hecker Fink effective Monday.
