A familiar face at ABC News is about to wind up a long and distinguished career.

Friday night's broadcast of World News Tonight with Charlie Gibson will be his last.

Gibson is retiring after more than three decades of covering Capitol Hill, co-hosting Good Morning America with Diane Sawyer and anchoring World News since 2006.

Gibson's former GMA co-host Diane Sawyer takes over as the anchor of World News on Monday.
