NEW YORK (October 4, 2012)--Ann Romney will guest-host"Good Morning America" next Wednesday.
ABC said the wife of Republican presidential hopeful Mitt Romney will be on hand at the morning news program during its 7 a.m. hour, joining George Stephanopoulos at the anchor desk,
Mrs. Romney will be filling in for co-anchor Robin Roberts, who is on extended medical leave.
ABC said it is in discussions with first lady Michelle Obama for a similar guest appearance before next month's election.
Stephen Colbert, Oprah Winfrey and the cast of "Modern Family" have also been tapped to substitute for Roberts, who had a bone marrow transplant last month.
Roberts' absence came as "Good Morning America" has overtaken NBC's "Today" show in the ratings after years in second place.
