Indiana Gov. Mike Pence has signed into law a religious objections bill that could allow discrimination against gay people. While speaking to a packed room at the Commonwealth of California Club on Monday, Sen. Bernie Sanders addressed the issues saying, “What Gov. Pence is doing is dead wrong. He is on the wrong side of history. People all over this country understand that civil rights means that we end discrimination against all people, whether they’re black, Hispanic, Native American or gay. That’s the America we have to fight for.”

Sanders voted against the so-called Defense of Marriage Act in 1996 which denied federal benefits to same-sex married couples is unconstitutional. In 2000, Sanders proudly supported Vermont’s move to introduce civil unions making it the first state where the Legislature passed a law legalizing same-sex marriage without being forced to do so by a court.
