As an addition to your request, I'd recommend reading some philosophy. If you want left-leaning, you can jump straight in with Marx, Foucault, and Judith Butler (some of my favorites), but you don't really need to.
I'd just recommend this because the news is useless without a meta-understanding of its purpose in public opinion, ideology, and power. If you want to skip dense philosophy readings, just make sure to ask yourself, "Who benefits from the story being told?" Try to seek out a large variety of sources in respect to this answer. The reason that this is hard though, I'll personally leave to Marx and Goldman.
