This breaking news piece alleges that a Kenyan relative of Barack Obama is living illegally in the United States. This report is largely based on unconfirmed statements from anonymous sources, and lacks factual evidence, in-depth research, sourcing and context. Though it's possible that the reporter's findings may be correct, it's premature to reach any conclusions on this topic until more verifiable factual evidence emerges.

This is a brief factual story concerning breaking news recently leaked by government officials. While there is no depth to the story (depth increased in later reports as reporters had time to dig), this is a reasonable first report.

I suppose it reports some kind of facts, derived from some kinds of sources, and notes one possible reason for its release now.

This news report has considerable journalistic merit. The authors provide much factual information. They state that they are uncertain about a relevant point rather than ignore it. They note the concern of the Bush Administration that such information not be released during the final days of the campaign.
