Antoinette "Toni" Bush, partner-in-charge of Skadden, Arps, Slate, Meagher & Flom’s communications group, is leaving the firm to become global head of government affairs for Rupert Murdoch’s News Corporation.

The move comes a month after Bush’s now-former firm helped News Corp., the world’s second-largest media conglomerate, reach a $139 million settlement of shareholder litigation stemming from the company’s high-profile phone-hacking scandal.
