In California, former special prosecutor Kenneth Starr has signed on to defend the gay marriage ban approved in Proposition 8. Starr gained notoriety in the 1990s when he led the impeachment investigation against President Bill Clinton. California Attorney General Jerry Brown has asked the state Supreme Court to overturn Proposition 8, saying the voter-approved ban on same-sex marriage violates basic constitutional rights. The Proposition 8 Legal Defense Fund says Starr will argue the case on its behalf in state court.
