Rosie O’Donnell, a multiple Emmy winner for “The Rosie O’Donnell Show” and former co-host of “The View,” is going to help fill the void at Oprah Winfrey’s Harpo Studios when Winfrey retires her nationally syndicated TV program after 25 seasons in May.

Chicago Harpo employees were told Monday that O’Donnell’s new one-hour daytime talk show, set to launch this fall on cable’s OWN: The Oprah Winfrey Network, will tape on Winfrey’s soon-to-be-vacated stage in the studio space at West Washington Boulevard and North Carpenter Street.
