Senate to vote on same-sex marriage bill; Mauna Loa erupts for 1st time since 1984

Congress is set to take up legislation this week to impose an agreement between railroad companies and union workers. Clark Ballew from the BMWED national union joins us. Then, we get the latest on Hawaii's Mauna Loa — the world's largest active volcano which erupted for the first time since 1984 over the weekend — from Bill Dorman of Hawai'i Public Radio. And, Columbia University law professor Katherine Franke talks about what the passage of the Respect for Marriage Act would mean. Utah County marriage clerks Russ Rampton and Ben Frei explain why they perform online marriage ceremonies for same-sex couples from countries where same-sex marriage is banned, even though it runs contrary to their church's religious teachings.
