NEW YORK (AP) - Comedy Central's "Colbert Report" is off the air and it's a mystery why.
    
An expected new episode of the show was replaced by a repeat on Wednesday. Comedy Central said Thursday's live show will be off, too.
    
The network said it was airing the repeats "due to unforeseen circumstances," but offered no other explanation. A person close to the show, who wasn't authorized to speak publically on the matter, told The Associated

Press that new episodes are expected to return soon.

 A publicist for Colbert declined to comment.
