Do we live in a new era of endless congressional political investigations?

I’ve had many discussions recently with conservatives about Hillary Clinton and, in particular, the numerous investigations of her and Barack Obama. 

One of the questions that came up was, what have congressional investigations been used for in the past and what are their limits? 

In my research, I stumbled on a wonderful, freely available document at the American Law Library titled “Congressional Investigations: A Bibliography” by Matthew Mantel. 

If this interests you, I encourage a full read. But I thought I’d summarize some of the key points here and talk about how today’s investigations differ from the past.
