congresswoman barbara lee voted for. some of these decisions ultimately you could argue paved the way for the very deep divisions and disunity that i think we see today. you know, i think that unity allowed us collectively to make decisions based to some degree on fear that you could argue may not have been perhaps the most politically estute and politically calculating decisions to have made. >> a lot of the decisions made by the presidents we saw yesterday. of course, starting with bush but this has transcended so many presidencies. what did you make of seeing bush and speaking yesterday, obama and clinton in new york, president biden, of course, president trump a little bit. but what did you make of that? >> i was so struck just by watching and hearing these presidents. it was literally we used the word book end a lot over the last several years, but this was a book end from president bush to president biden. and i was struck by just how interwoven their presidencies were. george w. bush was not elected because of 9/11.
