It's official: Christiane Amanpour to anchor ABC's "This Week"

As had been rumored for the last few days, CNN vet and international reporting star Christiane Amanpour is taking over the Sunday morning ABC chat show "This Week."

Amanpour is seen as a huge get for the Alphabet net -- and might be seen as a big morale booster for ABC News, which was recently smacked with word from division topper David Westin that a massive downsizing was imminent. On the flip side, it's a major loss for CNN, where Amanpour spent two decades as one of its most well-known correspondents.

Amanpour fills the void left when anchor George Stephanopolous moved over to "Good Morning America," which he now anchors with Robin Roberts.

Amanpour officially joins ABC News in August. In the meantime, Jake Tapper will fill in as temporary "This Week" host.

Here's the memo from Westin:

I am delighted to announce that Christiane Amanpour will join ABC News as the new anchor of “This Week.” A highly respected journalist recognized around the world for her reporting, she brings to her new position a wealth of experience and knowledge, as well as a deep commitment to bringing news of the world to the American people. She will also appear on all other ABC News programs and platforms to provide international analysis of the important issues of the day. And, she will be anchoring primetime documentaries on international subjects.

Christiane will join us from CNN where, for two decades she has reported from the world’s major conflicts, including those in Iraq, Afghanistan, Pakistan, Somalia, Rwanda, and the Balkans. She has received every major broadcast journalism award. A formidable interviewer, she has sat down in global exclusives with many of the world’s leaders and military chiefs from the Middle East, Iran, Iraq and Afghanistan to Africa, Europe and the United States.

More than once over the years we’ve talked with Christiane about her joining us in one position or another. Until now, it wasn’t the right time or the right fit. We are fortunate that this time it worked for Christiane and for us.

With Christiane we have the opportunity to provide our audiences with something different on Sunday mornings. We will continue to provide the best in interviews and analysis about domestic politics and policies. But now we will add to that an international perspective. All of us know how much the international and the domestic have come to affect one another – whether it’s global conflict, terrorism, humanitarian crises, or the economy. And our international reporting has long been a hallmark of ABC News, part of the legacy Peter Jennings left for us. Christiane will bring the international and the domestic together, in the interviews she does and in the roundtable over which she presides. Our audience has come to us for years to see differing points of views expressed in intelligent and compelling ways; now the different points of view will be expanded beyond partisan politics alone.

Christiane will be joining ABC News in August. Until then, Jake Tapper has agreed to become the regular, interim anchor of “This Week.” Ian Cameron will continue as executive producer. All of us owe a debt of gratitude to him and to Jake, Terry Moran, Jonathan Karl, Barbara Walters, Elizabeth Vargas, and Matthew Dowd for taking up the reins of the program during this transition. Thanks to their hard work and dedication we’ve maintained the high standards set by George Stephanopoulos before he left the program for “Good Morning America.”

Please join me in welcoming Christiane to ABC News.
