Sharyl Attkisson: President Trump's first executive order was the first step to repeal Obamacare.

      Now the debate is what to expect under Trumpcare. The Senate's top democrat, Charles Schumer, raised concerns this week.

      Sen Chuck Schumer: But scrap the whole thing and go back? A chaotic marketplace, inconsistent coverage, skyrocketing premiums? No way. Back to 40 million uninsured Americans, back to discriminating against women with preexisting conditions? No way. Mr. President, Democrats don't want to make America sick again.

      What does Senator Chuck Grassley of Iowa have to say about about the repeal of the Affordable Care Act?

      Sen. Grassley: Well I can give you general principles. Selling insurance across state lines, emphasis on health savings accounts, greater transparency of pricing by hospitals and doctors, medical malpractice court reform, doing away with individual mandate, doing away with the employer mandate, probably keeping preexisting conditions that you can't be denied insurance, keeping children on their parents insurance maybe till the age of 26, it’s basically to give everyone in America access to health insurance, continuing having lower income people to be able to afford it, and to be able to have no government involvement in the doctor patient relation.

      Sharyl: Are you confident when we look back in a year or two that we'll have something like that?

      Sen. Grassley: Absolutely. Because that's the result of the election. But importantly than the results of the election, it's a result of the failure of Obamacare when we were promised that if you wanted your doctor you could keep it, many people changed it, if you like your health insurance you can keep it, many people had to change their health insurance, if you are going to get your premiums reduced by 2500 then they went up 3500 with all the...not even including all the copays and all that that have gone out of sky. It's the failure of something that was done in a partisan way in Washington but if done in bipartisan way in the years of the Obama administration, it would be a success today.

      Sharyl: If the fix is done in a partisan way without Democrats on board, which is how it looks like it's going, will that succeed?

      Sen. Grassley: The only thing that can go without Democrats on board is repeal. The replacement has to be done in a bipartisan way because the 60 votes are going to be required of the US Senate, so it's going to have to be bipartisan and that's what's going to make it more reasonable and a greater future than what Obamacare has. And remember it took 3 years for Obamacare to be phased in, so it's going to take 3 years for its replacement to be phased in.

      Sharyl: If people are worried they're going to be left without insurance in the meantime what would you say?

      Sen. Grassley: Well there's two things that people don't have to worry about. Number one is scare mongers want you to believe we're going to do something with Medicare when we do something to Obamacare, but Medicare is not even on the table. That might be on the table sometime down the road because you have to do something to Medicare or in 15 years nobody is going to have Medicare and Medicare should be improved and maintained. The second thing is that if we pass repeal we aren't going to have health insurance. The phase in of the new program means that you're going to phase out what you have now. So people that have insurance under the exchange with a subsidy are going to be able to keep it.

      Sharyl: After a Republican summit meeting this week the pressure begins. Senator Lamar Alexander, head of an influential health panel, wants Congress to have a plan to "repeal and replace" Obamacare by March.
