I'm having a hard time answering this one, because I genuinely think that simply not watching or reading any news is probably a better choice. But I'm assuming that's not an option, and she thinks it's her civic duty to stay up-to-date on the news.

The least harmful option may be the homepage of her local newspaper. You'll have to actually read it though, a lot of these will be just as brain-rotting as a national news site.
