Former Carlyle Group executive David Marchick is rejoining Covington & Burling in Washington, D.C.

Marchick, who joins Covington as senior of counsel, announced late last year that he planned to leave Carlyle, where he served most recently as managing director and global head of external affairs and was a management committee member.

In his 12 years at Carlyle, Marchick was one of several executives that oversaw its transformation from a relatively low-key private-equity firm to a global, publicly traded asset management group.
