Campbell to replace Katie?

US News and World Report is claiming in its Washington Whispers column that NBC News correspondent Campbell Brown may be in line to replace Katie Couric as Today anchor. The magazine reports that Brown impressed NBC executives with her reporting from the Gulf Coast over the past few weeks. NBC hopes Couric stays, but realizes she is a top candidate to become an evening anchor at either CBS or ABC. Brown is currently a correspondent for NBC Nightly News with Brian Williams and a co-anchor for the weekend edition of Today.
