major setback for egypt. who is running the country? the constitution was ruled invalid today in egypt, and said that anyone elected under it has to go. egypt's military rulers took over all of the legislative pow, and it is already a tense time politically as the egyptian voters will choose a president in a runoff election this weekend. and the prosecutors in the jerry sandusky child molestation trial will wrap up the case today. one of the victims is an alleged victim whose mother called authorities after her son told her that he had showered with sandusky. he is accused of abusing ten boys in a ten-year period. this aircraft went down yesterday, and all five crew members are not injured, and the osprey's safety has been questioned since 2005. a man accused of a shooting spree in auburn university is accused of three murders and two assault counts. you can see desmonte leonard at his court appearance this morning. the funerals for the two killed will take place saturday, and two of them were former auburn university football players. it is not a good day for cyclist lance armstrong who is fighting a uphill battle, accusations he is a blood doper. today the world body that controls the races say he cannot compete in the race this month. but that is not the issue, because the administration may find a way to take away the seven world titles, which is a world record. and casey winans has more into new evidence of what lance armstrong is cited in the story as well. >> el ewell, fredricka, that is correct. the world anti-doping agency sent a letter to lance armstrong and in what is called a conspiracy to not only use enhanced performing drugs, but to traffic performance enhancing drugs. according to lance armstrong, he took to twitter as many people do these days and called it a witch hunt. he also released a for mall statement that said unlike many of my accusers, i have competed as an endurance athlete for 25 years with no spike in performance. also he says he has passed more than 500 drug tests and never failed one. he calls it a vendetta by former competitors and he calls it unfair. now sh now, there is a hearing that is expected to happen sometime before november, and even before that hearing the charges are going to go before a review panel, but lance armstrong is saying that these charges are basically based on old allegations, and cannot be proved, fredricka. >> we talked about the seven tour de france titles, but what else is at stake for armstrong? h. >> well, armstrong, himself, say says this is an effort to have the tour de france titles stripped from him. also, this as you mentioned, he has had a career recently after he retired from cycling of competing in triathlons and he cannot do that any longer while this investigation is under way. we should point out that the u.s. anti-doping agency says that all of the witnesses corroborated in the investigation of enhanced performance drugs in cycling and says that lance armstrong was given an opportunity to do so, but he did not and that is why he is facing allegations, and not all of the other cyclists who have admitted to using enhancement performance drugs. >> so this investigation is one thing, but might it lead to a potential criminal case? >> it does not appear so. lance armstrong was the subject of a justice department investigation, and that investigation was closed without any charges earlier this year. also a grand jury looked into this, and they did not return an indictment against lance arm strong, so it does not appear that any criminal charges will result of this. >> casey winans, thank you so much. >> the banned substance is called epo, and an athlete who uses it can manipulate the amount of red blood cells which can boost the athlete's performance. our medical correspondent elizabeth cohen is here, and what is epo? >> it stands for erythroprotein, and it brings more red blood cells into your blood, and more red blood cells increase the oxygen that your muscles can get. this drug is a wonder for aids patients or kidney failure patients, and you can see here the red blood cells and imagine more of those bringing more oxygen to your muscles. athletes have taken a look at this in the past and said, more oxygen to the muscles, and that would be good for us, too. >> if it is used in other patients with ailments including kidney patients, why would this be a difficult thing to detect? >> it is because our bodies naturally produce epo, and it took years for them to figure out a test to distinguish the natural epo from the kind of epo that you take as a drug. just because the drug exists doesn't mean it is easy to detect the levels in your bloodstream, plus, this letter they wrote to lance armstrong and others says that he did things to mask his use of epo, for example, they say he would take smaller doses so it is more difficult to track them, and he used masking agents and things that you can do to mask the drug in your system, and they say that he injected it into his veins rather than right under the skin. >> these are the allegations that are unproven. >> still unproven. >> so if you were an athlete who were to use the epo, and what potential side effects or dangers would there be to that user? >> epo can cause a lot of problems. what it does is to make your blood thicker and we saw before the red blood cells, you have thicker blood. if you have thicker blood, you are more in danger of having a stroke when things are so thick that blood gets to the brain. higher danger of heart attack, and anemia or sudden death in sleep. so if somebody is doing this -- >> over a prolonged period of time? >> well, it is not necessarily going to take all that long. there have been athletes who have suffered, you know, from using this, and it is not clear exactly how long they used it for, but this drug can be dangerous. >> well, that is fascinating, because he is still seemingly the picture of health, so all of the list of things has. happened. >> hasn't happened. >> because if those things are not absolutely going to happen to you if you use the epo, but it increases the chance that it is going to happen, and you running that risk. plenty of people use epo and that never happens. >> fascinating stuff. i know we will be talking about this again as the investigation continues to move forward. thank you so much, elizabeth cohen. appreciate it. that banned substance that lance armstrong is accused of using, we will keep you up to date as they work on that investigation. here is what else we are working on. they are among the most persecuted people on earth. we will tell you what life is like for muslims in myanmar. and the freedom tower is climbing higher everyday. tonight the president is working with union workers building it. and they are illegal immigrants. they reveal themselves on the cover of "time" magazine. ok! who gets occasional constipation, diarrhea, gas or bloating?
