News feeds are written in XML (generally). A google search for XML news feeds will then reveal what you are looking for, I'm sure. I would start with the BBC (for here in the UK), and I'm sure America has lots of great news channels also.
N.B. To add one to your site, choose a "viewer" from the web. Many are on http://www.dynamicdrive.com/dynamicindex18/index.html or you can use one of the many others out there. All seem pretty self explanatory and you can just add them straight on to your site.
