Hew, let's just start with trump ans former fer, ael Cohen. The white house, as you saw Na's piecehere, cut and said in essence don't believe Michael cohen,an admitted liar isn't there some truth to that? Is calling another person a liar. An, Donald Trump has his own credibilites in the course othis, bu guess is the southern district of new York and the speciounsel Robert Mueller understand the problems that Michael N has in his own credibility, so my guess is Ty have a lot of other corroborating evidence that will back up what he says and not rely solely on him but as I say, the presidwho as we know as "The Washington post" has documented has probably told 6,000 or so plus things that arena S his own es with thtruth. Let's talk now about the new acting chief of St Mick Mulvaney. He's coming into a west wing that been at Tim think it's fair to say turbulent.is mulvanekely to be able to have an im here? L, I -- fit find the designation as him as acting sort of very interesting becau nearly everyinet member probably cders themsves ontays and O goes. I thheo have to -- geral Kelly ie himain goal was to provide discipline to the white house. As we teg back he wasn't very successful. Whether ot Mick muaney will dat, the inresting ING, Mick Mulvaney will still keep his budline of hiin and now wh the health carsituation we're in will is probably going to be his main source of strength in THA usss about dplining th president and keeping on a straight and north more abohat does hdo about care so let'sp bko that cause it'our lead story this morning. The judge in Texas, the state where you reside, declth thaca is unconstitnal. Esident overnico out in support of that hailing it as a victory and also Cal on congress to com W new law to proviea to mons of ameca do you think that is likely to happen, that the Democrats and repuicans can aft somethre Well, for the president and the Republicans, I harken back to wisdom, wch is be careful what you wish for, and in tsituation Lilly, E Democrats are in a much better position. Thinkor three reasons if you think about it. One is, Obamacare, the afrdare act, more popular than it's ever been since it was passed. Tye country ts that. Two, as we saw in the general elecn Ms health care was a huge issue and advantaged Democrats by large amounts. It's ay of their strongest issues they have in running against it Andree, thisuilds momentum for what many of the Progressive des chcare for all. I think it's going to be almost impossible for the democ andthe Republicans and the president to come ther on fixing this because where the Democrats ard where thicans want to be, it's obviously it's going to go to the of appeals. There's some question on wheth not thisudge's ruling will survive, B I thinkor tical purpes, this is a major, major problem for republicans they Mo into the 2020 race and heightens the ability for ressive ATS to pusdi L.
