In Congress and the courts, gun control took center stage Monday. There was a partisan showdown in the Senate over four different measures.

Gwen Ifill talks to political director Lisa Desjardins, Marcia Coyle of The National Law Journal and Evan Osnos of The New Yorker about the debate on gun laws and gun ownership.
