Despite how many news articles can be found through Google, not all publications make their articles available for free. Try searching the news databases that the Tri-Co libraries provide to expand your research.
Access World News and LexisNexis are usually good places to start since they are large databases with broad coverage. However, the most relevant results for your research won't necessarily come up to the top of your search results. The advanced search features on these websites are quite powerful (e.g. limit results by date, geographic region, etc.) for sifting through large amounts of articles.
