Reporting on Bezos' affair legal, says tabloid accused of blackmail

National Enquirer tabloid's owner AMI on Friday said it acted "lawfully" in reporting on world's richest person Jeff Bezos' affair with ex-TV host Lauren Sanchez. AMI added it will "investigate" allegations of extortion made by Bezos. Bezos had alleged AMI wanted him to drop an investigation into how it obtained his private messages by threatening to leak his nude pictures.
