CBS News says Norah O'Donnell has been named its chief White House correspondent.
The network said Thursday that O'Donnell also becomes the principal substitute anchor for "Face the Nation," and will report for all CBS News broadcasts, including occasionally "60 Minutes."
She has been the chief Washington correspondent for MSNBC and a contributing correspondent for NBC's "Today" and "Weekend Today." She also appears regularly on "The Chris Matthews Show."
O'Donnell joined NBC News in 1999. Before that, she was a staff reporter for the Capitol Hill newspaper, Roll Call, and worked as a contributor and analyst for MSNBC.
Chip Reid, the current CBS chief White House correspondent, will become a national correspondent based in Washington.
