Liberty University doesn't release a comprehensive list of all its graduates, and famous alumni are not widely publicized by the university in the same way as some other institutions. Therefore, pinpointing definitively "famous" graduates is difficult. You'll find many prominent figures who *attended* Liberty, but completed their degrees elsewhere or didn't graduate at all.
To find information on specific individuals, you would need to research them individually. Many online biographical sources will list educational background, but the information may not always be complete or verified.
