we've got lori robinson from factcheck.org, angie holen from politifact and josh levs. next question, please? >> they're flying in, let's zoomment to screen right here. this one comes from alek who asks how many more billions will it cost the have government administer the public option? what have you found so far? >> what we are finding is the details of the public option are being negotiated right now or even if it will exist and that's a question, too. so the answer right now is it depends on how it's structured, it depends on the kind of bargain power it's going to have, so right now, we just can't say. >> lori, are you on par with that? >> definitely. we can't too much, up in the air about how thing will be structu structured. >> one thing we know is the cbo has said it's going to keep scoring these bills as it studies them until ultimately they can say we found one, this person is revenue neutral and that's apparently the version of the health care bill that ultimately be passed. and. >> and of course the big problem with this, josh, is anything they come up with
