The FBI is investigating British socialite Ghislaine Maxwell and several other people linked to U.S. financier Jeffrey Epstein, who killed himself while awaiting trial on sex trafficking charges, according to two law enforcement sources familiar with the investigation.

They said a principal focus of the FBI's investigation is Maxwell, a longtime associate of Epstein, and other "people who facilitated" Epstein's allegedly illegal behavior.

Maxwell has not been accused of criminal wrongdoing. Her lawyers Jeffrey Pagliuca and Ty Gee did not respond to a request for comment.
