Hillary Clinton's win in Puerto Rico's primary on Sunday did nothing to discourage Bernie Sanders, who opened a new line of attack ahead of Tuesday's California primary. Sanders, speaking on CNN's State of the Union, targeted the Clinton Foundation—and its willingness to accept cash from countries like Saudi Arabia—for the first time, reports the Guardian. "Do I have a problem when a sitting secretary of state and a foundation run by her husband collects many millions of dollars from foreign governments which are dictatorships?" he said. "You don't have a lot of civil liberties or democratic rights in Saudi Arabia, you don't have a lot of respect there for divergent, opposition points of view, for gay rights, for women's rights. Do I have a problem with that? Yeah, I do."
On Sunday, Sanders repeated his promise to push for a contested national convention, arguing that he is still lobbying superdelegates and polls show he has a better chance of beating Donald Trump, the New York Times reports. Both candidates spent the day campaigning in California, as did Bill Clinton, who told Sanders supporters they would be "toast," CNN reports. The former president singled out the group of Sanders supporters at a Los Angeles rally after shouts of "Bernie" began. "I don't want to pick a fight, but if I were them I'd be screaming, too, 'cause if you figured this out, they're toast for Election Day," Clinton said. He went on to describe his wife as the candidate for the working class and minorities but said: "I don't have anything bad to say about the people that are shouting against Hillary. I think at least we've had the right debate in the Democratic primary."
