thank you very much, ted rowland. >>> dr. sanjay gupta introduces us to glenn keller who drives 300 miles a week in the tractor trailer and doesn't leave time for health and fitness but three days away from competing in the first triathelon along dr. sanjay gupta and six other cnn viewers. >> reporter: nine months ago glenn keller pulled in to the parking lot of a walmart. he gave the last bucket of fried chicken and then bought a webcam and sent us this. >> i'm at least 100 pounds overweight. >> reporter: keller, also runs a call-in ministry from the truck weighed 315. could only sleep with the help of a machine to treat the sleep apnea and knew if he didn't change fast, he was headed for a disaster. >> we are delighted to invite you to be a member of the six pack next year. >> reporter: we selected glenn as part of the triathelon challenge. since that moment, his life has changed dramatically. at our first meeting, his spirit was more than willing but it would sake time for the body to follow. a few months later, we met up

ted rowlands is in chicago right now where the negotiations are taking place, and ted, first of all the chicago teachers have not gene on strike in past 25 years, and tell us what is behind this. >> well, there's a couple of issues that are yet to be resolved suzanne, and as you might guess pay and benefits. and the school consolidations, they want to protect the teachers and when they change the contract, they want to know what it means for them, the sticking points of breaks and that. and so there is also an anti-union sentiment percolating over the last year or so, and you can look to wisconsin and ohio, and they say it is playing a part in this as well believe it or not. >> it is playing a part. and what is most disconcerting is that you have democratic mayors all over the country leading the charge on attempting to destroy the public sector. particularly, you know, public schoolteachers unions. >> and of course, the democratic mayor in this city is rahm emanuel and we asked him for an interview to talk about that specific issue, but he declined. they did issue a statement, his offi

ted rowlands, cnn, aurora, colorado. >>> after months of criticism, presidential nominee mitt romney releases some tax records. and they reveal that he actually paid more in taxes than he had to. what's that all about? copd makes it hard to breathe, but with advair, i'm breathing better. so now i can be in the scene. advair is clinically proven to help significantly improve lung function. unlike most copd medications, advair contains both an anti-inflammatory and a long-acting bronchodilator working together to help improve your lung function all day. advair won't replace fast-acting inhalers for sudden symptoms and should not be used more than twice a day. people with copd taking advair may have a higher chance of pneumonia. advair may increase your risk of osteoporosis and some eye problems. tell your doctor if you have a heart condition or high blood pressure before taking advair. if you're still having difficulty breathing, ask your doctor if including advair could help improve your lung function. get your first full prescription free and save on refills at advaircopd.com. less e

ted rowlands explains what's going on here. >> reporter: as you might imagine, pay is one, another job security for veteran teachers when schools are consolidated or shut down. they want those teachers protected. another thing is chicago is extending the school day this year and want specifics laid out in a contract which the board has been reluctant to do. >> if the teachers walk off the job, chicago officials will open 144 sites across the city to give 400,000 students effected a safe place to go. >>> and cnn confirmed jesse jackson junior is back home in washington after being treated for depression at mayo clinic. we have been following this closely. the illinois senator, jackson has been out since may. we asked his chief of staff if he will be back to work when the house reconvenes, we heard we hope. we were speaking to him yesterday in charlotte. >> saw him in charlotte. obviously wish his son the best. >> it was fun, great to be part of the team, led by you. >> you did a good job. >> thanks, wolf. >>> big joint campaign event soon in iowa. the president, vice president, the firs

cnn's ted rowlands is in chicago watching all of this. ted, what's the status of the talks? what's going on? >> reporter: well, the talks are ongoing, wolf, which of course is a good thing. however, there's no indication that a deal is imminent, meaning most parents have come up with plan "b" and are expecting that their kids will be out of school again tomorrow. with their teachers on the picket lines, 350,000 chicago schoolchildren spent the day either at home or places like sweet holy cross church where the doors were open for kids to come to eat breakfast and lunch and watch movies. at this point, money doesn't seem to be an issue. teachers here make an average of more than $70,000 a year and have been offered a 16% raise over four years. the major sticking point is an valuation system that teachers believe will mean job losses. they also are striking because of the way they claim they're being treated. >> teachers are under pressure, nationally teachers are being demonized for the ills of society. teachers need resources and support. >> reporter: the focus of a lot of t
