ABC News Waylaid

ABC's "World News Tonight," scrambling to fill the gap left by its injured anchor, Bob Woodruff, is facing further instability: Elizabeth Vargas, Woodruff's co-anchor, is pregnant.
Vargas and her husband, singer-songwriter Marc Cohn, are expecting their second child in late summer, they announced Friday. The couple have a son, Zachary, 3, and Cohn has two children - Max, 14, and Emily, 11 - from a previous marriage.
Vargas, who with John Stossel also co-anchors the ABC newsmagazine "20/20," will continue to anchor both programs through late summer.

"I told Elizabeth that during such a difficult time for all of us, it's good to get such wonderful, life-affirming news," ABC News President David Westin said in a statement.

Vargas, 43, and Woodruff, 44, debuted as "World News Tonight" co-anchors Jan. 3.
