Elizabeth Vargas has told USA Today that she plans to "do everything in my power" to return as anchor of a nightly network news program. She said that her decision to relinquish her post as sole host of ABC's World News Tonight was "excruciatingly difficult" and complicated, but that she had little choice. Referring to her former co-anchor, BOB WOODRUFF, Vargas said, "We're a team. Bob and I are both reporters and wanted to be reporters first. We wanted to take the show on the road ... traveling to war zones. Now I can't even fly" (because of her pregnancy).
