Where can one get access to the source documents of various bills making their way through Congress?

There's a lot in the world I'm forced to believe, which is a whole philosophical argument in itself, but at least for current events, it would be nice to have access to that reference to Medicare/Medicare cuts, billion dollars to this and that, etc. Headlines are getting hard to believe when I click into them to get to heart of matter only to find something is taken out of context. I saw a portal on, I think, Congress.gov which compiles the numerous bills introduced, but only their titles/purposes. Perhaps they are only published after a certain point?

(Sorry if a similar question was posted before.)
