ABC’s Vargas is pregnant

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.

After Woodruff’s injury while reporting in Iraq Jan. 29, “Good Morning America” hosts Charles Gibson and Diane Sawyer have filled in on “World News Tonight,” and will continue to do so “for the next few weeks,” ABC News spokeswoman Cathie Levine said. “When we have more information about Bob’s recovery, we’ll put a plan in place to take us forward.”

Referring to any maternity leave Vargas might take, Levine added, “We’ll factor that in, as well.”
