Authors with different ideologies may differ on the meaning of the facts, but the facts of a story themselves should be the same, provided the source is ethical. If the facts of a story aren't reported by multiple sources or the details differ among the sources, consider digging further.
When verifying information through other sources, look for differences in reporting and emphasis. Use your judgment; are the differences innocent, or do you suspect a deliberate effort to mislead you?
