university even with the university property stamp on the back. we have a jacket that he wore. he as you can see when you look at the jacket, it's pretty torn up and ratty. he liked to keep the clothes for a long time and left the jacket hanging in the office going on the last trip to oxford, mississippi, when he passed away. >> on sunday at 12:00 p.m. eastern on american history tv, we'll travel to thomas jefferson's mont chel lo. >> if you visited, say, 20 years ago, you would have come up the mountain and you would have just seen jefferson's beautiful neoclassical villa but we wanted to change that, restore the landscape of slavery because if you mad come up this mountain top in jefferson's time, the first thing you would have seen most likely would be enslaved people. there would have been no place on this mountaintop that slavery was not visible. and we want to restore that, make that known to visitors who

come here today. >> we'll also visit the mill ir center at the university of virginia to learn about the first-year project exploring challenges u.s. presidents face in the first year on the job. >> as lyndon johnson said when he became president, no matter how big your majority is, you get one year before they, the congress, stops thinking about you, the president, and starts thinking about themselves, their own re-election and about january of your second year after you've done your first year, all the members of congress are thinking about their midterm election. and they're really cautious about taking any risk to help you get your mandate and your agenda through. >> watch c-span's cities tour of charlottesville, virginia, saturday noon eastern on c-pan span2 and american history tv on c-span3. working with our cable affiliates and visiting cities across the country.
