All right, robin, thank you. We know the vatican is especially important for robin. There before her own stem cell transplant. Well begin with that Severe Weather outbreak across the country.

Tornadoes spinning from california to kentucky. Its a tornado. It is. Reporter in standislaus county, trying to avoid the winds. Tornado on the ground. Tornado on the ground. Reporter the storms unleashing twisters, in some cases even two at a time. There it is. Right above us. Reporter recklessly slinging debris. This one rotating through central illinois. Another hitting southeastern nebraska. Holy [ bleep ]. Oh, my god. Reporter swirling peer inging close to homes. In oklahoma, hail smothering the roads. Most golf ball size, pretty difficult to walk out here. Its like walking on roller skates. Reporter across the state line in missouri this explosive supercell turning out a tornado windows of this church. Test. To the race for the white house. Shaking up the race. The republican nominee, but ted cruz is hoping his hail mary vp move can shake up the race. Its a long shot move by ted cruz to try to save his campaign. President of the united states, Carly Fiorina. Reporter cruz is tapping definitely comfortable as his Vice President ial running mate even though hes way behind and the primaries arent even over. I am prepared to stand by his side. To defeat donald trump, to defeat hillary clinton. Reporter as the president ial candidate fiorina battled with trump. I think women all over this country heard very clearly what mr. Trump said. Reporter since dropping out shes campaigned a lot with cruz and formed a bond with his family. Even singing to his daughters. I know two girls that i just adore im so happy i can see them more reporter but donald trump ahead by more than 400 delegates mocked the move. The first president ial candidate in the history of this country whos mathematically eliminated from becoming president who chose a vice okay. Reporter and after his tuesday sweep of the northeast, trump is kthing the next battleground state. Im not playing games with indiana. Reporter earlier in washington, trump showed his serious side. Outlining his Foreign Policy agenda in a formal address. America is going to be strong again. America is going to be reliable again. Reporter trump used his speech to outline a Foreign Policy vision that includes investing more in a stronger u. S. Military but also scaling back u. S. Involvement around the world. It was a speech, george, that was highly critical of the Foreign Policy of both barack obama and george w. Bush. Yes, it was, okay, jon karl, thanks very much. Lets check in with matthew dowd, our little analyst. I take it you think about this cruz fiorina thing the same way that trump does. I think its going to have zero effect. Behind and on a bad sixgame losing streak, adding up a relief pitcher who flushed out earlier by getting shelled isnt going to help you instill faith in your fans. And trump is staking such a strong claim now to the nomination with these votes. Hes been building them up week after week. Well, you take a look at where donald trump, the top three vote getters in the history of the republican history have been george w. Bush in 2000, donald trump second now and mitt romney third and so donald trump has a shot at winning more votes than any republican nominee has ever won in the primary process by the end of this process. He has a huge lead, george. Looks like we have a fall matchup. Yes, we do. I think the fat lady hasnt sung yet but shes walking up the steps and getting ready to go on stage.

Reporter american tells us it may have been two birds or more that that jet actually hit. Now, the nose is made of a softer material because electronics are housed behind it so they wanted to get it checked out. Take a look at this. I want to show you some video. This is slow motion of a Lightning Strike over west london. The British Airlines jet flying through a storm to heathrow, a passenger says they were shot by the loud noise and bright light.

We move on to a mumps outbreak at harvard. 41 cases have been confirmed even though many of those have been vaccinated. Linsey davis has the latest from boston. Edge. Reporter yes, good morning. Students on campus are telling us they are being extra cautious, no longer sharing food and drink, College Campuses are the perfect storm for outbreaks like this because the students are in such close contact. The number of mumps cases at Harvard University this morning is now up to 41. 11 of those students are currently in selfisolation. Harvard Health Services director paul bchltarreira says im more concerned now than i was during any time of the outbreak. Ive had a lot of friends that have it. Reporter the first case reported two months ago, all the immunized against mumps. Even after two doses of the vaccine, 12 of people are still at risk for contracting the virus according to the cdc. Mumps is spread in crowded environments by droplets of saliva from coughing, sneezing, shared eating utensils and kissing. Symptoms include puffy cheeks or jaw, fever, headache, muscle ache and fatigue. We heard its very contagious and there are a lot of people around us that have it so were a little scared. Reporter its shown up on four nearby campuses in the boston area. Another 53 cases at two universities in indiana and several cases in california. Harvards graduation is just four weeks away, students who are sick are being advised not to attend. Mumps can be serious but most people tend to make a full recovery in just a few weeks. Amy. All right, linsey, thanks so much. We have abc news chief health and medical editor dr. Richard besser here and we just heard linsey say most people make a full recovery but there thats right. Most people who get it, it is a typical viral illness with fever, body aches, fatigue and that telltale sign of mumps, the swells of the face. After puberty there is a risk for complication, inflammation of the testes and ovary, hearing loss that can be permanent and even inflammation of the brain. In terms of how this virus is spreading and who it may spread to, who is most at risk. Its prolonged direct contact so people who are sharing a room with someone with mumps, theyre at risk from sharing utensils and cups and from kissing. In the Greater Community they tend not to see spread. But its a good time for people to remember that two doses of the measles, much, rubella vaccine will decrease the chances that youre ever going to get mumps. Vaccinations do help.
