NORRISTOWN, Pa. — Bill Cosby's lawyers pressed a judge Tuesday to keep the comedian's damaging deposition in a decade-old lawsuit out of his sexual assault trial, saying Cosby agreed to answer questions under oath after being assured he wouldn't be charged with a crime.

The defense has insisted Cosby had an oral promise from the district attorney at the time that he wouldn't be prosecuted over a 2005 sexual encounter with Andrea Constand, a former Temple University basketball manager. The judge previously refused to dismiss the charges on those grounds.
