You can see that it's Washington Post, well-known both for its ideological bent and its owner, as is generally the case for all major news outlets. As I see it, you should (1) use it understanding that; (2) pick other major news publications whose biases your prefer, and/or (3) find outlets that you find to be neutral, understanding that they're probably small and you should keep knowledge of them to yourself, lest they should become very successful and thus worthy of being bought or steered into something you don't like.
