Time. He says hed rather spend these next few weeks gearing up for a showdown with Hillary Clinton. And speaking today on fox news sunday, trump was already talking like he is the presumptive nominee. Yes, its over. I think its over now, but its over. Cruz cannot win. Hes got no highway. Hes got nothing. Hes way behind. Im leading him by millions and millions of votes, and im leading him by 400 or 500 delegates. Meanwhile, ted cruz says the primary fight is far from over regardless of the outcome on tuesday. I agree that indiana is incredibly important i think regardless of what happens in indiana, donald trump is not getting to 1237. No ones getting to 1237 pop were headed to a contested convention. So we have fox team coverage. Kristen fisher following the democratic race. Lets begin with carl cameron whos covering the republican side. He is in indianapolis tonight. Carl, on the eve of indiana, whos the favorite . Reporter well, ted cruz set expectations very high, saying that he would win this red state after a spring of blue states on the east coast where donald trump had been successful. And it looks like he may not live up to his own expectations based upon the polls. Two new polls today came out. Both and each contradicting the other. First the nbc wall street journal poll. Cruz in the low 30s. Kasich withdrew from the state in order to give cruz the opportunity to maximize his opportunity. Then there was another poll that came out from the university of indiana and purdue out of its institute for politics. And it has it reversed. Ted cruz is the leader in the 40s. Donald trump in the 30s and then kasich again far off the pace. An average of the last seven polls here in indiana, only one is cruz actually leading. And yet he is absolutely defiant suggesting that even if he doesnt win, hell go forward which is telling. Hes now focusing on california for a justification to go on to the convention. And that theres just too much hype either way you look at it, its going to be close. Heres an example of how hes trying to fight back against what he says is the conventional wisdom against him. The Mainstream Media wants this race to be over. The new york power brokers want this race to be over. The wash waub lington lobbyists this race to be over. John boehner wants this race to be over. Theyve all made their decision. And how it affects the people of indiana. Reporter cruz has been advertising aggressively, focusing on evansville, terre haute, south bend. Here in indianapolis trump is expected to do very well. Cruz has lots of ads. Not so much for trump. Patti ann . Meanwhile, trump and heidi cruz actually on the same when it comes to an old controversy. Reporter yeah. On friday, little notice was heidi cruzs remark, campaigning alongside Carly Fiorina, ted cruzs wouldbe running mate, suggested that her husband could unite the party in part because hes an immigrant. And that caught the attention of donald trump who has long been saying ted cruz born in canada shouldnt be eligible for the presidency. Heres what heidi cruz said on friday. Ted is an immigrant. He is hispanic. We can unify this party. We have libertarians joining our cause. I have people every day from the Democrat Party telling me that they reregistered to vote for ted as a republican so they understand what he stands for and he represents american values. Reporter mrs. Cruz also made the argument that ted cruz is much stronger than women than donald trump would be. Heres trumps response with a decided emphasis on an issue he was eager to talk about, ted cruz being from canada. About heidi cruz whos a very nice woman said my husband was an immigrant. Oh. It became a big story. Because ive been saying that, hes an immigrant, he cant run for president but she said, my husband was an immigrant. I guess thats in front of a group of people. Ive been saying that. Now, i dont want to cause any problems. And its not going to matter. Reporter both cruz and trump are campaigning here in indiana tonight. Most folks wont be looking for politics. Theyll be looking for the pacers in the nba playoffs. Patti ann . Carl cameron in indianapolis, thank you. And turning now to the race for the democratic president ial nomination, Hillary Clinton and senator Bernie Sanders, both busy on the campaign trail today. Clinton getting ready to deliver the keynote address at detroits naacp dinner. Earlier she stumped . Indiana at a getoutthevote rally. Senator sanders is also in the Hoosier State holding a rally in south bend. Indiana voters make their choice for the democratic nomination on tuesday. 83 delegates are up for grabs. Kristin fisher is live in washington with more. Hi, kristin. Where does the race stand now . Reporter patti ann, clintons ahead but not that much. A new poll out just this morning has clinton ahead by only four points, 5046. Even if sanders win indiana, it likely still wont be thuf to catch up to clinton in terms of delegates which is why today sanders went after the superdelegates. At a press conference here in washington to commemorate the oneyear anniversary of his campaign which was yesterday, sanders singled out superdelegates in states where he beat clinton by a wide margins. States Like Washington and minnesota. And he asked the superdelegates in those states who are supporting clinton to reconsider. I would hope very much that the superdelegates from those states where we have won with big margins or, in fact, where secretary clinton has won with big margins. To respect the wishes of the people of those states and vote in line with how the people of that state voted. Reporter so sanders is saying wait, theres still a way. But the Clinton Campaign is already moving on to the general election. Staffers are being september out to the november swing states where attorneys are starting to scrutinize possible runle mates. And even clinton herself is now making the case publicly that it may be time for sanders to get out. There comes a time when you have to look at the reality. In fact, in 08, i was much closer in both popular vote and pledged delegates to senator obama than is the case right now. Reporter now, today clinton was in indiana. Later this week shell be in california. But behind the scenes, her campaign is taking very clear steps that signal they believe this primary battle is over. Patti ann . But sanders still raising millions for his campaign. Caller right. Just this morning his Campaign Announced they had raised 26 million in the month of april. That sounds like a lot of money, and it is, but its a lot less than the 46 million that he brought in in march. When you take that combined with the fact that he had to lay off nearly 200 staffers last week, those are the clearest signs yet that this may be a campaign thats winding down. Patti ann .

In an interview with cnn, the president said it was their best chance to get osama bin laden. And if they didnt, it could have been years from they were able to find him again.

Who fired the fatal shot that killed bin laden described that very moment in a fox news special in 2014. Standing on two feet in front of me was the face that i had seen thousands of times. Ubl.
