the united states and china are pledging to work closer together to achieve nuclear security. the chinese and american presidents met during a nuclear summit in washington, d.c. china plays a key role in enforcing sanctions against north korea, which has nuclear weapons. minimum wage earners in new york will be getting a raise. the governor and legislature have agreed to phase in the state's minimum wage to $15 an hour by late 2019. u.s. presidential candidate donald trump met thursday with the head of the republican national committee. >> the party source says they talked about delegates. they talked about convention rules and the state of the race. our ryan nobles takes a look at the numbers involved to get that republican nomination. >> reporter: donald trump is currently in the best position to win the republican nomination. but he may need every day of the primary process in order to seal the deal before the convention comes to cleveland in july.

trump currently stands at 739 delegates, and there are three types of states that have still yet to vote. you have winner-take-all state, hybrid states which award their delegates based on a combination of the results in the congressional districts and some other standards, and proportional states which award their delegates based on the overall vote total. let's assume trump continues at the same pace as he has throughout this primary process. and we'll award him all of the winner-take-all states, 76% of the delegates in hybrid states and 49% of the delegates in proportional states. now if we were to do that, trump would be at 1,138 delegates before the last day of voting on june 7th. but june 7th is a big day there are some big states voting, including california and new jersey. there are 303 delegates at stake. but if trump were to perform at the same clip, as you can see, he would easily get over the

1,237 mark and win the republican nomination. but this is an unpredictable election. a lot could happen. let's say donald trump do as well in the hybrid states and we drop his performance to only 50% of the available delegates. watch how the number changes, and he comes dangerously close to that 1,237 mark. and let's say he loses some winner-take-all states like montana and nebraska. if that were to happen, he would actually fall below the 1,237 mark and we could be headed to a contested convention. so as you can see, a lot can happen over the next several weeks. but right now the delegate math shows us that donald trump is in the best position to win the republican nomination. in washington, i'm ryan nobles. >> ryan, thanks. and when it comes to math, ohio governor john kasich presently has no mathematical chance of winning the republican delegate count outright. but he is stay manage the race. >> yes. the governor says he thinks he

is in a good position to come out in top in a brokered convention in which no candidate has the majority of delegates in the first round of voting. >> ted cruz needs about 90% of the delegates going forward to win. that's just not going to happen. and trump needs about 60%, and that's not going to happen either. look, when delegates go the a convention, and i've been at conventions, they get to be very serious about two things. one, who can win in the fall. and i'm the only one that consistently beats hillary clinton. and secondly, delegates feel the weight of decision on their shoulders. and they begin to think about who actually could run the country, who has the experience, who has the vision, who has had success in the past. >> we'll just have to keep watching to see what happens. but you of course can get your fix any time on our website. we have the latest polls, election results and in-depth reporting. you can find it at cnn.com/politics. now to a fight for a level playing field in the world of soccer.

players on the u.s. women's team are calling for equal pay to their male counterpart citing better results and stronger financial returns. they've been winning. the women filed a complaint wednesday evening with the equal employment opportunity commission. that's the u.s. agency that enforces equal pay law. goalkeeper hope solo explained the decision to nbc's "today" program. >> it's a pain to be told we can be grateful just to have the opportunity to play professional soccer and to get paid for doing it. and in this day and age, you know, it's about equality. it's about equal rights. it's about equal pay. and we're pushing for that we believe now is the time is right because we believe it's our responsibility for women's sports. >> right. >> and specifically for women's soccer. >> and the numbers are on their side. they make for a strong argument here. male players can earn more than $17,000 for an exhibition match against a top opponent, according to the court document. and they get no less than $5,000

even if the team loses. but women are paid a maximum of less than $5,000 even if they win every game. the men's team earned $9 million in the 2014 world cup for losing in the round of 16 while the women made just $2 million when they won. the 2015 championship. the u.s. governing body released a statement reading the following, quote, u.s. soccer will continue to be an advocate on the global soccer stage to influence and develop the women's a game. and involve fifa's compensation model. notably, it did not give any specifics on the compensation model. >> earlier i spoke with sports commentator, the author of end zone, the rise and return of michigan football. i asked whether the women were making a valid case for equality in this case. >> it should be noted also that the women's team itself has

generated more money by far, by $20 million last year in 2015 than the men's team did. so their case is not only based on how well they're getting paid but how much they're winning, but how much money they're generating for the u.s. soccer federation. by those three bases right there, pretty clearly they should be getting paid at least as much as the men. they might even argue more than the men. >> can i ask you, is the reason they're generating more money, does that come down to their generating more interest because they're a hot team? >> winning does sell, doesn't it? it certainly does help. furthermore, in the u.s., of course, and you know being an american, that with title ix, there are millions of girls who revere these women as their heroes. they have a natural base of fans. men and women watch the game. and tim howard, a former men's star and landon donovan have already come out strongly in favor of this action. so they've got the support i think almost the entire nation.

>> you've got this marquee, if you will, lawsuit. because looking at the them now, these are the stars of the u.s. women's soccer team. so this case, john, could become a touchstone in the debate that we're hearing in the election cycle about the pay gap between men and women. couldn't it? >> i dare say it will be. in fact, you have to say the women, their timing could not be better. they won the world cup, of course, last year in canada, 2015. and they won three of those. they made more money than the men. it is an olympic year, 2016, of course, in rio. and trust me, the u.s. soccer federation, the usoc, even ioc has to have the american women there in order to get american tv ratings. and it's one of the craziest election cycles of all time. one of the items on the docket is fair pay for women, of course. this feeds exactly into all those agendas. i think their odds of winning are excellent. >> and i want to ask you this.

if these women prevail and they likely should, what do you think we will hear as far as, will we, the reasoning that it hasn't been fair? >> man, we're dealing with irrational behavior, you'll get irrational answer, of course. you're going to claim it's less popular. it's not. they're going to complain that they're not as good. that's not true. they're world cup champions. any logical reason that you can give me that they're not to be paid the same simply breaks down very quickly. so you're going the hear all kinds of crazy stuff. but it will be crazy stuff. the women here have got in my opinion a rock solid case. >> we look forward to the outcome. and we look forward to seeing what you write about it. john bacon joining us. thank you so much, john. >> natalie, thank you. >> and of course, when there is an outcome, you will hear it here. go, gals! >> absolutely. >> they're winning. >> they're wing. just ahead here on

we could see some localized flooding. here are some of the tornado reports we had earlier. it's still a very volatile situation across the deep south. but now we're starting to see an increase amount of lightning in south central sections of georgia and still lingering in alabama. although it looks like it's calming down because you don't get the heat of the day. with the cooler temperature, you're not going see the thunderstorms fire up quite a bit. but this area of low pressure, you can see this on the water vapor imagery, this will move across the great lakes. this is a clipper system. they call it a clipper because it moves so quickly. but then as we go towards the weekend and then into monday, those temperatures are going to be remarkably cold. april is just one of those fickle months you can never count on it. back to you guys. >> thanks, karen. well, one of the world's most innovative architects has

welcome back to "newsroom." south africa's highest court has ordered president jacob zuma to pay back part of the $15 million that he used to renovate his private residence. after an investigation in 2014, the president was ordered to reimburse the government for upgrades not related to the security of the home, like the swimming pool and the amphitheater. >> but mr. zuma never paid the money back. on thursday, the court said his failure to do so violated the constitution. >> all the president was required to do was to comply. arguably, he did, but only without reporting to the national assembly. the president has thus failed to

uphold, defend and respect the constitution as the supreme law of the land. >> president zuma says he will now cooperate with the ruling. in the u.s. state of alabama, governor robert bentley is refusing to resign in the face of a deepening scandal over an alleged extramarital affair. >> his top aide, the other woman named in that alleged affair has now resigned from her position in the governor's office. here is cnn's alina machado. >> today i want to apologize to the people of the state of alabama. >> reporter: alabama governor robert bentley under fire, but refusing to resign after being accused of an affair with one of his top aides, rebecca mason. the allegations surfaced after sexually explicit recordings of him became public. >> i stand behind you, and i put my arms around you, and i put my hands on your breasts, and i put
