Trump appeals ruling requiring him to testify in New York investigation

Lawyers argue ordering Trump and two children to testify is a violation because answers could be used in a parallel investigation

Donald Trump has appealed a judge's decision requiring he answer questions under oath in New York state's civil investigation into his business practices - a widely expected move that's likely to prolong the fight over his testimony by months.

Lawyers for the former president and his two eldest children filed papers on Monday with the appellate division of the state's trial court, seeking to overturn Manhattan judge Arthur Engoron's 17 February ruling.
