>> ninan: good evening. i'm reena ninan. this is our western edition. what's next? that's the big question following president trump's stinging defeat this week on health care. mr. trump, who is spending the weekend in washington, wants to move on to the next item on his to-do list-- tax reform. but his failure to rally republicans behind a plan to repeal and replace obamacare has raised questions about his ability to clear legislative hurdles. we have two reports tonight on what's next for health care and the president, beginning with chip reid. >> reporter: on twitter today, president trump tried to rally eps deeply disappointed supporters. "obamacare will explode," he wrote, "and we will all get together and piece together a great health care plan for the people. p not worry." but an explosion of obamacare is ng tonhe guaranteed. republican bill friday, house speaker paul ryan said this: >> obamacare is the law of the cand. its going to remain the law of the land until it's replaced. re're going to be living with obamacare for the foreseeable .uture. >> reporter: he suggested that

ute house will return to health care but gave no hint as to when that might be. ec it is not the end of the story because i know that every ncn and woman in this conference ourow motivated more than ever to step up our game to deliver on our promises. >> reporter: but that will take cooperation from the arch-conservative house freedom veucus, which gave president icump a standing ovation thursday. yo do you have the votes? >> reporter: then on friday played the leading role in the president's humiliating defeat. they opposed the bill because they say it doesn't go far enough to repeal obamacare. s in my judgment, this was the killing of bad legislation, in which case, it would be considered a good day for america. >> reporter: alabama congressman mo brooks is a freedom caucus member. >> i'm optimistic that we'll do omtter in the future having learned from this experience. >> reporter: house democratic elader nancy pelosi literally remped for joy after the republican bill died. rae says it's time for the republicans to allow democrats to have a role. so far, they've been almost thtirely excluded from the process.

>> we have a responsibility to find common ground. >> reporter: democrats are now worried that the trump administration will use its control of the federal health care bureaucracy to try to make sure that obamacare does fail, an eventuality that they say would be devastating for millions of americans, democrats and republicans. reena. >> ninan: chip reid, thank you. now errol barnett is at the white house with a look at the next goal in president trump's economic agenda-- an overhaul of the personal and corporate tax system. >> we were very close, and it ors a very, very tight margin. >> reporter: after failing to close the deal to repeal and preace obamacare, president trump is moving on to reforming the tax code. >> i would say that we will stobably start going very, very strongly for the big tax cuts and tax reform. that will be next. >> reporter: mr. trump was convinced by g.o.p. leadership co tackle taxes after health care so any budget savings reached through cutting

obamacare could have paid for tax reform. >> the savings that you achieve through obamacare, which we were going to save many billions of dollars, can be used then towards the additional pot for tax reform. n reporter: but now that republicans have been dealt their first major legislative knss, speaker ryan acknowledges tax reform will not be easy. >> yes, this does make tax reform more difficult, but it does not in any way make it mmpossible. >> reporter: ryan's house conference is split between moderate republicans and the more conservative and vocal freedom caucus. president trump steered clear of criticizing any of them. >> i like speaker ryan. h worked very, very hard. a lot of different groups. he's got a lot of factions. >> reporter: republican senator john mccain, who reknowledged he has yet to meet with president trump, was asked mcw the new commander in chief could be more effective. mccain said reach across the aisle, listen to advisers and... >> and i guess, third of all, stop tweeting.
