donald trump. yesterday she called him a loose cannon. the republican though is firing back and he insists he can reshape the electoral map and win the white house. as the dust settles in the republican primary, party leaders are weighing in. house speaker paul ryan telling cnn he can't currently support donald trump. >> i'm just not ready to do that at this point. >> reporter: in an unusual move, the last two gop presidents -- george h.w. and george w. bush -- say they'll sit out this election and will not endorse trump. and the last republican nominee, mitt romney, says he'll skip the convention this summer. hillary clinton shoring up support in california and slamming trump. >> trump turns around and says, i don't care if other countries get nuclear weapons. that is the kind of risk this country cannot afford to take. >> reporter: clinton leads trump in head-to-head polls. in the likely republican nominees facing challenges with the electoral college map. the states

presidential elections. if clinton can hold on to those she just needs to win florida to win the white house. >> you have to be able to expand to the map to places like michigan and pennsylvania. the problem for donald trump is before he gets to geography, he has to deal with demography. and donald trump, before he even starts picking states, has to fix his problem with latino voters and his problem with women voters. >> reporter: and on cinco de mayo, trump tweeting this message. and clinton pouncing. meanwhile, bernie sanders keeps up his push for the democratic nomination saying he is going to stay in this race until the last primary. but yesterday, diane and kendis, some pretty strong words from hillary clinton. not so subtle hints that she thinks sanders should bow out. >> never a dull moment, karen, thank you. former republican presidential candidate ben carson says that he won't be donald trump's running mate but he is hopie in helping with the for one. carson tells "wall street journal" a democrat could be i

considering anyone who puts america first. the fbi has interviewed hillary clinton's top aides as part of its investigation into her use of a private e-mail server. sources tell abc news that includes human may abba dine, considered clinton's closest adviser. that means clinton is likely next to be questioned, probably in the next few weeks. clinton says she's ready to answer questions and is confident that "nothing inappropriate took place." president obama has commuted the sentences of 58 convicted criminals, including 18 who were serving life sentences. that boosts his total to 306 granted petitions, more than the previous six presidents combined. the president also urged congress to overall sentencing guidelines, particularly when it comes to nonviolent drug convictions. to canada where the raging wildfire is driving one of the largest evacuations in north american history. more than 80,000 people have been forced to leave their homes in the heart of canada's oil fields and thousands more are

today if conditions are safe enough. the fires have burned an area larger than new york city. at this point officials say the only thing that will stop this fire is rain. air tankers just aren't doing the job. >> dramatic scenes there in alberta, canada. dramatic scenes south of the border. to another huge fire at a houston warehouse this morning. it is finally out. the video shot by drones shows the thick black smoke and flames shooting dozens of feet into the air. but now officials say pesticides and other hazardous chemicals got into the water supply nearby and they're warning residents to stay away. here's abc's matt gutman. >> holy moly. >> reporter: that towering firestorm at this warehouse complex near houston -- >> there's another one. >> reporter: starting as a house fire. 20 minutes later the four-alarm fire exploding setting off this chain reaction explosion. one warehouse after another. >> another explosion right there. >> reporter: 3,000 residents bordering the complex were told

the hot spots and the all-clear has been issued after that shelter in place. but the concern now is that pesticides have leached into the soil here and could run off into local waterways. matt gutman, abc news, houston. we have a verdict in a notorious grim sleeper case in los angeles. former trash collector lonny franklin jr. was found guilty of murdering 10 women over the course of more than 20 years. prosecutors plan to seek the death penalty when that phase of the trial starts next week. the killer was called the grim sleeper because of an apparent 14-year gap between two of those shootings. the federal government is taking a major step to keep e-cigarettes out of the hands of young people. the food and drug administration is banning the sale of electronic smokes to anyone under 18. and if you're under 26, you'll need to show photo i.d. to buy them. the change also means e-cigarettes will be regulated by the feds. the new rules take effect in august. if all goes as planned there will be 20 horses

tomorrow's kentucky derby and this year did you know the 142nd running of the race? >> at this point the early favorite is a horse named nyquist. he's at 3-1 orders right now. he'll be wearing number 13 tomorrow. he's undefeated 7-0 so far in his career. >> jackie victor espinoza who rode american pharoah to triple crown glory will be riding number 10, whitmore, tomorrow. right now he's at 20-1. nyquist sounds slow, sounds like nyquil, he'll be sleeping. >> our favorite is the number 2 horse. >> sudden breaking news. >> that's who we're going with. >> it's going to be like when "sopranos" ended when everyone thought there was something wrong with their cable? everyone will think there's something wrong with the banner when we report he won. that's who we're rooting for. >> next year's running will be the 143rd. >> oh, wow, look at you. justin bieber put on a show last night athe

(laughing) (colonial penn jingle) you may know what it's like to deal with high... and low blood sugar. januvia (sitagliptin) is a once-daily pill that, along with diet and exercise, helps lower blood sugar. januvia works when your blood sugar is high and works less when your blood sugar is low, because it works by enhancing your body's own ability to lower blood sugar.

or low blood sugar (hypoglycemia). januvia should not be used in patients with type 1 diabetes or diabetic ketoacidosis. tell your doctor if you have a history of pancreatitis. serious side effects can happen, including pancreatitis which may be severe and lead to death. stop taking januvia and call your doctor right away if you have severe pain in your stomach area which may be pancreatitis. tell your doctor right away and stop taking januvia if you have an allergic reaction that causes swelling of the face, lips, tongue, or throat, or affects your breathing or causes rash or hives. kidney problems sometimes requiring dialysis have been reported. some people may develop severe joint pain. call your doctor if this happens. using januvia with a sulfonylurea or insulin may cause low blood sugar. to reduce the risk, your doctor may prescribe a lower dose of the sulfonylurea or insulin. your doctor may do blood tests before and during treatment to check your kidneys. if you have kidney problems a lower dose may be prescribed. side effects may include upper respiratory tract infection, stuffy or runny nose, sore throat, and headache.

ground after seven people were hurt on this allegiant airlines jet, a flight from the dominican republic to pittsburgh which diverted to ft. lauderdale after hitting what the airline called unreported clear air turbulence. first responders saying four flight attendants and three passengers were taken to the hospital. some with head injuries. that incident on the heels of this dramatic turbulence which had passengers praying. the woman who took this video says there was no warning of the severe turbulence. >> everything just shock. the plane went up and down. a lot of people on the plane, they didn't wear seat belts, you know. so they're like flying. >> reporter: pictures of the aftermath showing a cracked ceiling, aisles littered with debris. 31 people were hurt, nine taken to the hospital from the flight to jakarta. turbulence injuries are relatively rare in the u.s., but these incidents can be

david kerley, abc news, washington. coming up in our next half hour, there were laughs all around at joint base andrews as president and mr. obama kicked off the 75th anniversary of the uso. what jon stewart said about donald trump and who was that guy in the beard? that's ahead in "the skinny." "shark tank's" corcoran explains her controversial tweet about yanking up skirts to get ahead. what she says moms should be telling daughters about how to get ahead in business.

she's one of the most famous business women in the country but barbara corcoran's latest piece of advice isn't sitting well with feminists.

she said that to succeed in a man's world, she wears bright colors and yanks up her skirt to get attention. >> now she's getting plenty of attention. and refusing to back down. abc's amy row back sat down yesterday on gma. >> i happen to have great legs. i didn't have the best face or the best body but i had great legs. if i wanted to get attention i'd make sure i'd wear my skirts really high, yank up my skirt at the midriff, and walk into a room and everybody notices me because i've got great legs. i think it's a great gimmick if you are smart enough to get attention. i don't think that's sexual in any way. but that's what makes a horse race, right? >> i think a lot of people are upset about that yanking up your skirt because it seems to imply that you're using your sexuality to get ahead in business. you say you don't apologize for that and flirting is a technique for you sometimes? >> it certainly is. and think about it, amy. what do men do? smoke cigars

flashy in the ferrari, wearing the rolodex watch, playing golf with their bosses. they've got all the gimmicks going that make them belong and be a little different and a little bit part of the boys' club. women don't do those things. if you're attractive, it's one thing to build up your numbers in business and get a tremendous balance sheet and in the end you're judged by that in business. it has nothing to do with male or female, you're judged by your numbers. but to get to those numbers you've got to stand apart from the pack. you will never succeed being exactly like the next guy or gal because nobody will notice you and you'll never get to that juicy balance sheet that every woman out there building a business is hoping to get to. >> barbara, this is not a new message for you. you've written books. i love this title. "if you don't have big breasts, put ribbons on your pig tails and other lessons i learned from my mom." why wouldn't you tell women to use their brains instead of their breasts? >> let me tell you something. if you're not using your brains you're not going to succeed in business. it is not an easy game to build a business. you have to be thinking all the

common sense and great intelligence to build your business. that's a given. but assuming you have five people with equal intelligence working equally hard, the person who knows to grab attention is going to be the one that gets noticed and gets put ahead. look at our phenomenal donald trump. could you even imagine, if he was saying these sound bites that he's throwing out there, if he were a woman? he'd be thrown out of the country. he's using the male macho gene all way. but no criticism on that, no. >> do you think women using sexuality is comparable to cigars and male prowess and talking about a woman's physical appearance and body parts with so many women trying to say, my looks don't define me, what do you tell your young daughter as a lot of us moms with daughters are trying to tell our daughters the exact opposite message? >> i'm sorry, i wish i would agree with you. you know how i love you so much a .

my whole life. i'll tell you if you can grab attention and be different from the pack, and it doesn't have to be in any sexual way. men will go out and buy a $5,000 tom ford suit to impress their friends, okay? they know they're looking good. they know they're strutting their stuff. i think it's the wrong message to tell young women they should look leek the guys. i don't think it works in business. if you're beautiful, let yourself be beautiful. i just feel like you should use whatever you've got to your own advantage. i see it as the only way to get ahead in business. >> advice from barbara corcoran. she by the way worth personally $45 million. >> you kind of have to listen to a little bit at least. >> you might not agree with it all but i think she kind of summarized it at the end. she's not saying to be sexual necessarily, just to use whatever you have to kind of grab people's attention and engage. >> it's an interesting message, especially as amy was pointing out to young girls. good on her, she's 67 years old, she has legs she i

working everything she can. >> working it to a $45 million net worth. why just shave, when you can choose to smooth? choose suprises over dull. choose design, over in a lull. choose for women. choose leader. choose bars. choose movement. choose delight. choose to love your knees and treat your underarms like queens. choose skin you adore. choose venus. choose more. choose to take a stand. choose to smooth. venus

time now for "the mix." kind of a nice touch for the gamers. a man in texas goes to a yard sale and buys a box of old video games, paid $80 for roughly 40 games. >> okay. >> one of those games, however, it turns out, was a 1987 track and field game called "stadium events." he went on google. come to find out he sold it for nearly $8,000, a collector's item. sold to it a private buyer in denton for $7,500. only 200 known copies of that video game in the world. >> very cool. >> two bucks in, nearly $8,000 out. >> you can't necessarily afford this next item. take a look at this. the most expensive airline

you might say in the world. it's now a suite. it's a one-way ticket from mumbai to new york city with a stop in abu dhabi, $38,000. >> what do you get for $38,000? >> 125 square feet suite, bigger than the average new york city apartment. it can seat three people. that's three beds. >> three beds? >> yep. flat-screen tv. >> take it one way. >> and personal polka. ♪ ♪ politics and foreign wars all the weather all the scores ♪ ♪ that's the world news polka ♪ if you're an insomniac and a good night's sleep you lack ♪ ♪ do the world news polka ♪ it's late at night you're wide awake and you're not wearing pants ♪ ♪ so grab your "world news now" mug and everybody dance ♪ ♪ on the town you and me there's a lot for us to see ♪
