senator from michigan and now bernie sanders supporter don riegle. thank you for joining us tonight. >> thank you, lawrence. thank you for the job you do. i see you all the time but -- >> it's good to see you, senator. what i'm doing is as easy as it looks. but senator, i have to tell you, i'm very surprised. if someone asked me who's don riegle going to back i would have said he's going to make the conventional choice in this situation, a former senator, he's going to go with the former senator, he's going to go with hillary clinton. i remember watching you in the senate working with hillary clinton, working very hard to get her health care plan through the senate finance committee, trying to get that passed. how did you make this decision? how did you come out this way? >> well, you know, i served over the time he, 28 years in the congress, seven different presidents. you get to see different kinds of presidents and different kinds of presidential styles. but the whole political system has changed. and you know that almost better than anybody else
