Transcript for Hillary Clinton, Bernie Sanders Both Take Aim at Donald Trump

His name is figure nothing Tuesday's California primary where Bernie sanders and Hillary Clinton are going head-to-head in what's expected to be a close contest but they're saving their biggest champs for Donald Trump. We have the story right there in California from David Kerley. Reporter: Good morning, the man would wants to make America great again is coming under fire this morning for expressing his admiration for the greatest. Donald Trump's rivals are calling him hypocritical. It all started with trump tweeting his respects for Muhammad Ali or as he put it, a truly great champion and a wonderful guy. He will be missed by all but on Saturday trump's opponents reminded him of the attacks the gop has made against Ali's religion. Don't tell us how much you love Muhammad Ali and yet you're going to be prejudiced against muslims in this country. Reporter: It's really troubling to see someone seeking the most important job probably in the world who talks about people like that. Talking about not letting any more muslims in America. Reporter: Muhammad Ali himself called trump out after that mass shooting in San Bernardino when trump proposed banning all Muslim immigrants from entering the U.S. Until our country's representatives can figure out what the hell is going on. Reporter: At the time Ali said in a statement "Speaking as someone who has never been accused of political correctness, I believe that our political leaders should use their position to bring understanding about the religion of Islam." On a day that we are mourning Muhammad Ali, it's worth remembering that we live in a country where people can break down barriers where they can worship their own god. Reporter: Trump told "The new York times" he didn't think that Ali's San Bernardino statement was referring to him and an Ali family spokesman reportedly said that Ali was referring to jihadists and extremists, not to trump. Right, that's an important piece of context. Thank you for your reporting. Let's bring in George stephanopoulos who has an exclusive interview with Hillary Clinton. How is it going? In your interview with Clinton she goes hard at Donald Trump yet again. What do you think of this new tough stance? Is is it working. It's firing up her supporters. No question about that. I think a lot of democrats are looking to that and saying she's doing what we hoped she would do for a long time. Remains to be seen how that will will play out over the next five months when she wraps up the primaries but I do believe if the Clinton camp can maintain this kind of sustained attack, it will put Donald Trump on his heels, one of the things you've seen for the last couple of days he's not diving the news cycle as much as her attacks have been driving the news cycle. Before she takes him on fully, though, she has to get through the primaries. Big one coming up in Tuesday. If Bernie sanders wins there, how much does that weaken her? It's not going to help and I think it guarantees he stays in through the convention but even if Bernie sanders wins in California, it's all but certain that Hillary Clinton will have the pledge delegates, enough delegates to secure the nomination at about 8:00 Tuesday night once the votes come in from New Jersey. She won the Virgin Islands yesterday, likely to do well in Puerto Rico today. Fewer than 60 delegates away from having the delegates she needs to get the nomination. Almost -- the math doesn't work for Bernie sanders here. Could be embarrassing but it won't change the outcome so one last question, in your interview you pressed her hard on the ongoing e-mail controversy. How much of a cloud is this over her campaign. It continues to dog her and had that tough state department inspect report that I questioned her about where she said it was not approved. She doesn't accept that conclusion. I think that she's going to continue to fight on that. The big question is going to be what does the FBI do and tells me she still has not been Koo kooktkoo contacted by the FBI. If she's indicted all bets are off but she and her team say that is not going to happen. Gi, thank you. George's interview with Hillary Clinton will air later this morning on "This week" right here on ABC. Let's things over to Ron
