Journalists Gwen Ifill and Judy Woodruff will be the new co-anchors of the PBS NewsHour, the network announced on Tuesday.

The change marks the first time two female news anchors will host a major network evening news program together. Ifill and Woodruff are expected to begin their new roles in September.

“Gwen and Judy have been the heart and soul of NewsHour for years,” NewsHour executive producer Linda Winslow said. “It’s wonderful to formalize these new roles and give them an opportunity to provide even more input on the content and direction of the show.”

Ifill and Woodruff will anchor together Monday through Thursdays; Woodruff will anchor solo on Fridays so that Ifill can fulfill her duties as host of the PBS program “Washington Week.”

PBS also announced journalist Hari Sreenivasan will be promoted as senior correspondent for the NewsHour. Sreenivasan will also anchor a new edition of PBS NewsHour that will air on the weekends starting September 7.
