A lawyer for President Donald Trump and his children asked a federal appeals court Tuesday to force arbitration in a lawsuit alleging that they, and the Trump Corp., illegally profited from promoting doomed products and services to unsophisticated investors across the country.

Thomas McCarthy, a partner at Consovoy McCarthy, told a three-judge panel of the U.S. Court of Appeals for the Second Circuit that a district court judge had incorrectly barred Trump and his children, Ivanka, Eric and Donald Jr., from availing themselves of arbitration agreements that unnamed plaintiffs had entered with ACN Inc., the multilevel marketing company at the center of the allegations.
