. >> and back with me is david thornburgh, president and ceo of the committee of 70, a watchdog group that monitors corruption in philadelphia and state elections as well. david, you just saw the story. are you surprised this is going on? >> well, i follow pennsylvania politics and politics around the country for a long time. this is behavior that happens from time to time. there's no good excuse. there really isn't. people need to know that their legislators are there and voting for bills, particularly important ones. so there really is no excuse. >> it may seem obvious, but why should our viewers care about votes cast by lawmakers who are may not be on the house floor? >> well, it raises all kinds of questions about the integrity of the process because now you don't really know who's voting for what. frankly -- and i understand the pressures of being a legislator. it's a busy job. there are votes coming up left and right. but you know -- and they're very sensitive to being present for votes. that having been said, it doesn't excuse letting somebody else vote for you. >> in this day
