Hi there - answers below: 1. We have a list of about 1000 news sources that we pulled together from lists of popular news sites and Twitter.

2. We use a 5-point political spectrum: Right, moderate-right, Center, moderate-left, Left.

Political leaning data is from Media Bias Fact Check and AllSides. The methodology of these sites seems reasonable and they've been used in research by The Economist to study bias on Google search results so we consider that to be generally acceptable.

2A: Breitbart is Right-leaning.

2B: We don't have an "objective" tag. Most news sites consider themselves objective but the biases of the authors and news outlets - conscious or otherwise - suggest every story needs to be corroborated across a few sources.

The bias of an outlet doesn't affect its rating from The Factual. So the bias information is mainly for context to the reader and the fine gradation of Left vs. Moderate-Left may not be as critical.

Thanks.
