WASHINGTON (AP) — Another unfavorable decade-old television clip of tea party favorite Christine O'Donnell has emerged, this time with the Delaware GOP Senate candidate saying she "dabbled in witchcraft."

The clip spread among websites as O'Donnell canceled appearances Sunday on two national news shows. Her campaign said she had to back out of the programs because of scheduling conflicts with events in Delaware.

Since O'Donnell's upset of nine-term Rep. Mike Castle, opponents have unearthed unflattering age-old television clips. The most recent was aired by comedian Bill Maher, who dug up one of O'Donnell's appearances on his "Politically Incorrect" show in 1999.

The context of what led to her comments is not clear, and O'Donnell is laughing while she talks.
