News Corp. has bolstered its PR arsenal with Sard Verbinnen & Co. and Glover Park Group amid the U.K. hacking scandal that has tarnished the media giantís image.

SV, based in New York, and D.C.-based Glover Park will help the company present its case to media, investors and Capitol Hill as the story continues to simmer and federal authorities look into allegations of possible hacking in the U.S. at the behest of lawmakers.

The firms join Edelman and Rubenstein Communications which are counseling News Corp. execs, including CEO Rupert Murdoch.

Bloomberg first reported the PR moves noting News Corp. has lost $8B in value since the scandal flared in early July.
