administration, this strategic patience clearly not the strategy of the trump administration. so you have two american professors, kim hak-song, tony kim, they were teaching at a university in pyongyang, they haven't even gone on trial yet. you have kim done chol, a naturalized u.s. citizen sentenced to ten years of hard labor on spying charges. now the united states has to try to get these american citizens home. in terms of other potential retaliatory action they're really limited. they could impose more unilateral sanctions but north korea is already very heavily sanctioned. they could put more pressure on china to do more as they've been doing about the nuclear and missile programs. but at this point the number one priority of the united states has got to be to try to secure the release of these remaining three u.s. citizens. and to continue to encourage americans not to travel to north korea. >> will ripley, will, thanks very much. up next a fight over the health care bill escalating tonight with senate democrats trying to bring the chamber to a halt to protest the republicans' closed door process to get obamacare. the question is can they actually succeed? more on that.
