profit institutes we prostitutes were brought back to a hotel that was supposed to be as secure as a bank vault. should the rich pay more and can president obama be trusted with your money. and the final journey of the space shuttle "discovery" is a jaw dropper. even as the white house officials come to the defense of the agencies embattled director, mark sullivan tells susan collins as many as 21 women were involved and the implicated agents range from newcomers to some with 20 years experience. i spoke with the host intelligence committee member and former presidential candidate michele bachmann. >> this is an organize glags that we've trusted over the years and that is why it's so shocking. clearly this didn't just happen overnight. clearly this seems to have been a culture that was fostered over time. members of congress are taking this very seriously and we want answers. >> jessica yellin is joining us now. you have new details about the involvement of members of the military in this highly embarrassing series of events? >> reporter: that's right, john. this person says that this investigation they believe will ultimately find that all of the following u.s. military personnel were involved in this scandal. i'm going to look down at my notes. there were five army special forces services involved, marines that belonged to an explosive detection unit and one member of the air force. additionally, another u.s. member says an investigator has been dispatched to colombia to investigate the situation. this is separate and apart from the investigation that the secret service is investigating. john? >> that leaves us just shy of a dozen members of the military. 11 secret service members involved. it sounds like at least for now the white house is standing by director mark sullivan. is that fair? >> reporter: yes. it's absolutely more than fair. jay carney says that the president has confidence in mark sullivan that he acted swiftly and appropriately in starting an investigation and keeping the president informed of what's going on, that the white house would like the secret service to handle the investigation and that it is their responsibility to do it sort of separately and on their own and that the white house respects the secret service for what it does every day. basically, it's their job and let them do it. and the way -- what i hear and sense, john, is that the white house really doesn't want to have to get involved in this one, more than they already are. and that they don't sense political fallout from this, at least not yet. john? >> at least not yet. our chief white house correspondent, jessica yellin. as of now, no indications of any major lawmakers suggesting that he is imperiled. also, one of president obama's biggest re-election worries, that is the price at the pump. he talks about a five-point plan. the president defended the need for new regulations by talking football. >> imagine if the nfl quadrupled the number of teams but didn't increase the independent of refs. you'd end up having havoc on the field. and it would diminish the game. it wouldn't be fair. that's part of what's going on in a lot of these markets. >> my favorite referee, chief business correspondent, ali velshi is here. how would this work and would it actually work like the president thinks it will, bringing down the price at the pump. >> the regulators have to keep up with the changes, that the people who they are regulating are undergoing. so people who trade oil or commodity or stock these days are so sophisticated. they have great technology and can get trades faster than anybody else. the government has to be able to keep up with that. the question of of all of our viewers, absolutely not. i would be surprised if this has any impact at all. here's what the president called for. number one, he wants to boost the oversight that the security -- the commodity's future trading commission has over the trading of oil. he wants to increase funding six-fold. he wants to increase the fines ten-fold on people found to be guilty of manipulating the price of oil and he wants to raise the margin requirements. if you buy stock of general electric, you've got to put all of the money down for those shares. when you trade oil, you only have to put down 5, 6, 7%. if you have more skin in the game, you'll be less likely to manipulate. the example i ought to give you is back to the housing crisis. so many things went wrong with the people who valued your home, the bankers who sold you your home, fixing all of those things that went wrong doesn't fix the price of houses. the president is right on to want to fix them, completely wrong to suggest that somehow this will reduce the price of gasoline. >> you heard the president, when it comes to the markets and the price, who's the realville la v? >> there are a lot of people who say -- everybody is a speculator. everybody who has bought a house in this country is a speculator. there's nothing wrong with speculation. what the president should have been talking about is price manipulation. people who manipulate the prices. who is involved in the market for buying and trading oil. there's the producers, the people who buy oil futures because they have to sell oil and guarantee that they get a good price regardle of where it goes. then there are consumers. i've used as an example, airlines. airlines buy a lot of oil. they want to know how much it's going to cost them. then there are investors, people that have nothing to do with needing the oil. they don't produce it. they don't take delivery of it. they see it as an alternative of investing in the real estate market. nothing wrong with that, john, no matter what anybody says. there's nothing wrong with that. that's like me buying a house because i think it's going to go up. that is not illegal. and then there's people who take advantage of the differences in the markets. these are banks. these folks may have some impact. it's hard to tell how much in the price of a barrel of oil or gas. when we have found price manipulation in the oil market, that's where we have generally found it. that's where the president's reforms will come into play. ultimately it's not a big part and i'm going to get a lot of tweets about this. it's not a big price part in the price of oil. >> the president unlikely to get what he called for any way. the leading republicans in congress calling it a big gimmick. thank you for helping us break that down. here in washington, a magnifisence sight in the sky. you see the space shuttle "discovery" that flew in low over the monday mu meant destined for a museum outside of our capitol. this pilot initially goes where he's supposed to go but then takes a detour. what was that all about? >>. >> reporter: well, this was probably the biggest victory lap you could have for the shuttle program. "discovery" got this piggyback ride on the back of this modified 747. they flew over us at dulles and then over you in washington. i know staff snuck out over the windows to take a peak. what is going on is ffor people see this lap. "discovery" has come to an end. "discovery" flew 139 missions and actually spent a year in space if you logged all of the time together. it was a very important part of rebuilding the shuttle program after the disaster. the program in '86 was a fateful year for nasa. what you have now for folks is a chance to get up close with discovery. it will replace the "enterprise." that will go to new york. "discovery" will come in here. >> getting a shuttle that weighs over 200,000 pounds off the top of a 747, despite your help and i know you work out, how are you going to make that happen? >> reporter: this process is called demating. it will take about two days. they will lift the "discovery" off of the top of that 747 and it will come here. it will actually go nose to nose with the "enterprise." they will sort of point at each other. by friday people can come in and look at "discovery." the enterprise will go up to new york. eventually all of the different shuttles still around, that were part of the shuttle program, will reside in places where americans can come and get a chance to look at them, get a chance to look at part of what was a very storied u.s. shuttle program that had a 30-year run. john? >> lizzy o'leary, thank you so much. as we move on, more than two-thirds of the people that we asked in our polling says the tax system is unfair. it favors the rich. stand by to find out why washington can't or won't do anything about it. michele bachmann tells me why she's not yet ready to jump on the mitt romney bandwagon.

can they learn from each other? >> well, look. i think the romney plan is not fully specified. we heard the day before yesterday from the fund-raiser that the romney campaign is proposing to limit some deductions but the number of deductions they proposed to limit is far lower than the tax cuts they are proposing. so they are actually just proposing a multitrillion dollar tax cut heavily weighted to high-income people. i think we tried that approach specifically through the 2000s and it's not pro growth. someone needs to come up with the evidence that that actually works. >> it's a strong political argument if you can make the case. this is where george w. bush tried. how is the environment any different? >> first of all, we need to reduce spending both from what bush spent and certainly we need to undo the massive over spending that really kicked in. trillion dollar deficits that the obama administration started in the next 15 years are going to be the 15 largest deficits in the history of the country. so we can see what he's planning to do to us. we already know this because he ran four years ago, swearing up and down, again and again and again, he'd never raise taxes on anyone, any way, anyhow for those who earn less than $100,000 a day. two weeks into his presidency, who did he tax? buffett? rich people? no. cigarette smokers. average income, $40,000. the only rich person in the country who smokes cigarettes is named barack obama. we already know his promise not to gut the middle class and there's seven taxes on the middle class in obamacare directly. we know that he's going to raise taxes on the middle class. he's already started to do it now. his promises aren't worth the paper they are written on. >> the president in the past has infuriated liberals. if the jobs report next month and the month after is anemic, would he drop this buffett rule or is he locked in here? >> you know, i'm not sure what the hypotheticals are. the previous statement that grover made was outrageous and not believed by anybody who's anywhere remotely near the center of the party. as i've said, the president cut taxes for the middle class by $400 billion. the fact that a guy going to a suntanning parlor, that there's a health tax associated with suntanning parlors does not change the fact that the share of income that people in the middle class are paying in taxes is the lowest in 65 years. the president cut their taxes dramatically and overwhelmingly. >> the taxes are low because there's a recession and the economy is lousy. that's why the tax burden dozen low on everybody. >> the president passed the working pay tack and increase tuition credits for people whose kids go to school. we can go down the list of -- >> the promise is he wouldn't raise -- >> the president promised through the campaign. no. the president promised through the campaign that he would pass the children's health initiative. >> and not raise other taxes. >> grover -- >> he said it again and again and again. the president's own words. you can't use an etch-a-sketch and make the president's promises go away. that won't work. he lied. >> the president said that we needed a children's health initiative, which the bill was drafted before he was ever elected and includes an incredits in the cigarette tax. he promised that he would sign it because it was that important. to say that he was breaking his promise, it wasn't that he specifically said that he would sign a bill that was already in practice. once he got into office, he cut taxes for middle class people. by 400 billi$400 billion. so to say that he raised taxes on the middle class is totally not true. >> the argument for the deficit, if you look at our polling again, they say it would be okay if it's part of a bigger package. what's wrong with it? >> the president has made it very clear, whenever he gets additional money, he spent it. do you believe that obama will use any tax increase to reduce the deficit? the answer is no. >> feisty disagreement on this tax day. we continue 200 days before the election. austan, grover, appreciate your time today. bad news for mitt romney. dig deeper and find tonight's truth. romney's fortunes are actually on the rebound. and, next, a beautiful glass trophy means atlanta national football champ.
