Diane Sawyer to Anchor 'ABC World News' From Memphis
Diane Sawyer is traveling to Memphis to report live Monday from the communities bracing for flooding.
As the Mississippi River continues to swell, Sawyer will anchor ABC World News from Tennessee, taking viewers inside the flood zone, which has threatened nearly four million Americans. She'll also connect with local families as they deal with the disaster.
She'll also delve into the state of the levees and floodgates, and what happens if they fail.
Jon Banner is the executive producer of the broadcast.
