Barack Obama to appear on Fox News

Candidate will make exclusive appearance Sunday

NEW YORK -- "Obama Watch" is coming to a close.

After several weeks of counting the days since Barack Obama promised Chris Wallace that he would appear on "Fox News Sunday" -- 772 -- the campaign agreed Thursday to an exclusive appearance Sunday.

It will be Obama's only appearance on a public affairs show and comes five days after his defeat in the Pennsylvania primary. Wallace said Obama will be the only guest on the show, which will probably also have a segment with the regular panel.

Wallace, whose show airs on Fox Broadcasting stations coast to coast as well as Fox News Channel, started the feature in early March after multiple tries to get the Illinois senator on the program. But 772 days refers to how much time had elapsed since the Gridiron Dinner in 2006 where Obama first told Wallace that he would appear on the show. The "Obama Watch" had rankled the campaign, but Wallace told The Hollywood Reporter on Thursday afternoon that it wasn't just that that brought Obama to the program.

"They realized they've got a problem after Pennsylvania," Wallace said. "In the end they do it for their own reasons, not ours. But they realized he needs to be able to reach out to working-class, blue-collar Democrats, moderate to conservative, and that's our target audience."

Hillary Clinton has already appeared on the program twice.

Wallace said that he was told by the Obama campaign earlier in "Obama Watch" that the feature was obnoxious.

"My response now is that it was obnoxious and effective," he said.
