"When you find a news source that you trust, please let me know"  I think you have an error built into your query.  

A single source or fountain of knowledge, particularly in a world as inter-connected and complex as we live in  today is impossible.  The same is true of a single political party being an exclusive source of one's information.  

I research across multiple sources of information not just to embarrass 'True Believers" who think they have the God-given answers from Olympus to all questions about everything and post them on this site (although it is entertaining) but to compare different perspectives on different subjects to attempt a synthesis of what most accurately reflects reality.  

Please note, I absolutely, positively Did Not Say "Truth", but rather perceived reality. 

I can't think of any other solution and believe that the multiplicity of viewpoints, from the clearly insane to the other end of the spectrum may assist in my attempt to define reality.
