An inside look at Congressional Democrats’ gun vote sit-in

Democratic representatives took to the floor of Congress Wednesday for an all-night sit-in, demanding a vote to prohibit people on the “no fly” list from purchasing firearms. Political director Lisa Desjardins reports on the protest, and Judy Woodruff talks to one of the sit-in’s organizers, Rep. David Cicilline, D-R.I., about the necessity of the Congressional standoff.
