let's bring daniel brown back in. thanks for staying with us. in terms of the race to mars, what do you think the stakes are for that? is trying to fd?k each mission whato you think they are trying to prove? >> i think the big part is life, understanding was there life there, and being theirst to find definitive traces of that is a big one. the second is related to that very strongly. this robot has the possibility to look for ice, slushy stuff but still water. the proposed and soon to land rover from the chinese mission as well will do similar things. again, thinking about human missions to mars, that is a key thing, so that is one part. the other part, trying to understand more about how the climate on mars developed. i think it is being able to get, understand mars, find water, and i personally think it is being able to have a more sustained travel to mars and being able to go for humans on mars. why not? that might be the next step. >> indeed. i know you will be up for a committee to film it. let me pause you and bring in our correspondent i

. >> our next guests are part of this move: daniel gathers and jason carroll, brown university student first black woman to become student body president at m.i.t. you were already in that roll over the summer when we saw the protests after the killing of george floyd. how did those events change you, and what changes are you pushing for? >> i'm incredibly honored and humbled to serve in this role. i think being the first black woman student body president reminds me of my role and the need to expand the way m.i.t. thinks about diversity. i think we do a great job of thinking about diversity and equity and inclusion on campus. but i want to expand as one of the top schools in the nation, thinking about racism on a national scale and what we can do, thinking about the racial wealth gap and how m.i.t. can potentially play a role in lessening that gap. excited thinking about using black-owned banks, black investment managers and from the financial component what can we do to contribute. >> i want to pick up on that with jason. over at brown university i believe the african-american popula

professor brown, your book on errors of the founders, henry clay, john calhoun and then daniel webster, the second generation of american giants is a definitive exploration of the relationship and ideas of two of the clay and webster, both of whom influenced lincoln so begin by helping us understand the different ideas of clay and webster so that we can have a sense of them and then maybe help us put lincoln's concern about mobs in the broader context or the fact that this is a time when there are also mob actions against the federal army by john brown which you write about in your your book on john brown and lincoln suggesting in that circumstance mobs could be used in an effort to inspire us to slave uprising which failed. tell us about lincoln's attitude for john brown's action and what it says about his distinction between reason and passion. >> that's a tall order. the first thing i think to remember in all of these is definitely in the case of henry clay and daniel webster and abraham lincoln is these were men who made politics their profession and they understood that in politic

daniels. so, this was team seven, and that's what team seven looked like, but when you look at that republican vote, it could have been linus and charlie brown. this is a story art republican subservience. it's also always going to be the day that the gop broke up with the constitution. one of the most compelling parts of the case made by house impeachment lead manager jamie raskin and his colleagues was that the actual text of the constitution holds for a remedy precisely like what is on the table and that the republicans are staring at their toes and fidgeting in their seats and doing paperwork instead of looking at what they enabled, instead of looking at what they ushered in is the story. it is the twin headline with retraumatizing and reliving the attack on the capitol. i think the other headline out of that vote is that chuck cooper, who is, again, someone with nothing to lose or with nothing to gain, everything to lose, professionally, reputationally, and perhaps even socially, i don't know if some of these people are personal friends, he went out there and told the truth. they are now impervious to the truth as a political party. the
