John Horn, the former U.S. attorney for the Northern District of Georgia, has returned to King & Spalding as a partner in the special matters practice, as the firm calls its white-collar group.

Horn became the U.S. attorney in Atlanta in 2015, when his former boss, Sally Yates, became the deputy U.S. attorney for the Obama administration. He was succeeded last October by BJay Pak, the Trump administration appointee.
