And we will all get together and piece together a Great Health Care plan for the people. Do not worry. Former Obama Administration officials say, that partly depends on him. When he says, this thing is going to explode, is part of that in his power . Its a little bit like inheriting an overseas war and deciding youll let the soldiers get killed because it wasnt your idea to enter the war. Reporter in other words, a lot depends on how the administration decides to implement obamacare Going Forward. There is a way to get the law more to their liking. They could decide to undermine it at the expense of millions of people who depend on obamacare. Paula . So many headlines.

The president said watch jeanine about whether this was the right way too go first with the repeal. Apparently he said several times in internal meetings, we should have gone with tax reform fit. It was never a very first place. Remember, back in october, after access hollywood had the tape come out, paul ryan sai good public front. A cplorm you have the chairman of the Freedom Caucus on the show this morning. The conservative legislators who defied the president on health care. How big a challenge will this group be for the president Going Forward . Bigtime. It appears theyre not afraid to buck him when they need to.

Its a lot more difficult to pay for a new tax given that you dont have now a trillion dollars that they were counting on a trillion, a trillion that they were counting on on obamacare. Theyre going to push him hard on the debt limit. The president s budget doesnt have a path toward a balanced budget. This is just the begin of course what is likely to be a very fractious relationship. George stephanopoulos, thank you very much. George has a big show this morning. Hell go one on one with chuck schumer. And also, as we said, the house Freedom Caucus chair, mark meadows.
