NEW YORK (AP) – The National Enquirer’s alleged attempt to blackmail Amazon CEO Jeff Bezos with intimate photos could get the tabloid’s parent company and top editors in deep legal trouble and reopen them to prosecution for paying hush money to a Playboy model who claimed she had an affair with Donald Trump.

Federal prosecutors are looking at whether the Enquirer’s feud with Bezos violated a cooperation and non-prosecution agreement that recently spared the gossip sheet from charges in the hush-money case, two people familiar with the matter told The Associated Press on Friday.

The clash between the world’s richest man and American’s most aggressive supermarket tabloid spilled into public view late Thursday when Bezos accused it of threatening to print photos of Bezos and the woman with whom he was having an extramarital affair.

He said the Enquirer made two demands: Stop investigating how the publication recently obtained private messages that Bezos and his girlfriend had exchanged. And publicly declare that the Enquirer’s coverage of Bezos was not politically motivated.
