Sawyer has kept a low profile since giving up the reins at ABC's nightly newscast. The veteran journalist lost husband Mike Nichols in November. Her first report is a passion project of Sawyer's, whose doggedly reported on issues facing women over the course of her career. Her next project, not yet scheduled, will focus on women in prison. It will mark her third report on the subject over the past two decades, and it will air as a special.

As for her Nightline piece, Sawyer has partnered with New York Times columnist Nicholas Kristof to expose how sex trafficking is taking place in plain sight at New York's Port Authority bus terminal. Kristof premieres his latest PBS miniseries on sex trafficking, A Path Appears, on Jan. 26.

When Sawyer announced her World News departure last June, it was noted that she would head her own unit within ABC News and continue to produce and anchor her own specials.
