CQ Researcher provides in-depth weekly reports on current and controversial issues. After you click on the link, simply perform a quick search in the box at the top of the screen. Keep in mind this site covers broad issues, so here it is best to use broad terms when searching (i.e. "gun control", "health care", etc.). In a CQ Researcher report you will find a general outline of the topic as well as statistics, a pro/con discussion, and many references for further research.
