The website for the United States Selective Service System says registering for the draft is plain and clear: "It’s What a Man’s Got to Do. It’s quick, it’s easy, it’s the Law." And while no one has been drafted into the U.S military since the 1970s, men ages 18 to 25 are required to register in the event the military needs them.

Now, Colorado U.S. Reps. Mike Coffman, and Jared Polis, a Republican and Democrat respectively, have introduced a bill to do away with the agency. They argue it's costly and unnecessary. Another bill in Congress would require women to sign up along with men.  

We speak with Coffman and Christopher Capozzola, a professor of history at the Massachusetts Institute of Technology.
