Fox News Lineup Begins to Take Shape

Tucker Carlson, a former co-host of CNN’s “Crossfire” and a prominent conservative writer, is set to take over the Fox anchor chair at 7 p.m., filling the slot formerly held by Greta van Susteren, who left the network in September.

.. Mr. Carlson, 47, is in some ways a throwback to a more genteel era of conservatism. Preppy and jovial, Mr. Carlson founded The Daily Caller, a provocative, if relatively moderate, right-leaning website, and he has often evinced a mischievous streak; in 2006, he agreed to be a contestant on “Dancing With the Stars,” although he was eliminated in the first round.
