an individual like putin who clearly does not care about women and children and people who are infirmed and continually bombs where he knows where these individuals are trying to just survive, these are not military combatants, these are civilians, and he continues to do it. that's what makes it difficult. and getting the aid into the areas where these individuals are and/or getting them out of the danger that they're in. >> so today you and your republican counterpart, congressman mike mccall, introduced legislation to try to hold putin accountable for war crimes. how exactly can you hold him accountable from thousands of miles away? >> the first thing that you have to do is to make sure that you're able to obtain and keep and preserve all of the evidence that you can. and so that's what we're doing. we're saying that we will never, ever forget the damage that he's done to ukraine.
