NEW YORK (AP) — Oral Roberts was blind-sided by allegations that the university he founded was being exploited by his son and daughter-in-law, the aging televangelist said Tuesday in his first public comments on the case.

Roberts phoned CNN's "Larry King Live" to weigh in on the accusations leveled in a lawsuit by three professors who claim they were fired from Oral Roberts University for questioning the school's spending and students' involvement in a political campaign.

"Like my son says, it was a surprise and sort of a shock, but we have been through some tough experiences in building Oral Roberts University in the 1960s, and we have surprised them all and have built a university that we believe is for the glory of God," Roberts said,

Roberts, 89, spoke from his home in California as his son, Richard, and daughter-in-law, Lindsay, sat on King's set in New York.
