Here’s where Republican senators stand on the health care bill

WASHINGTON (CNN) -- Senate Republicans rolled out their health care plan Thursday, and within hours the bill was already on shaky ground.

Republicans can only afford to lose two of their 52 senators for the bill to pass.

As of Friday, most Republicans are still reviewing the text, but here is what many have said so far:

Opposes in current form but open to negotiations: 5 

Sen. Dean Heller (Nevada) -- Heller said that the Senate Republican health care bill "is not the answer. It's simply not the answer. And I'm announcing today that in this form, I simply will not support it. (Comments made at a news conference 6/23)

Sen. Rand Paul (Kentucky) --  "The current bill does not repeal Obamacare. It does not keep our promises to the American people. I will oppose it coming to the floor in its current form, but I remain open to negotiations." (Paper statement on 6/22)

Sen. Ted Cruz (Texas) -- "The current draft does not solve the problem, but I've been working to an agreement. People are unhappy with premiums because it has caused premiums to skyrocket. The current draft made this morning doesn't do what we need to fix that problem." (To reporters on 6/22)

Sen. Ron Johnson (Wisconsin) and Sen. Mike Lee (Utah) -- "Currently, for a variety of reasons, we are not ready to vote for this bill, but we are open to negotiation and obtaining more information before it is brought to the floor. There are provisions in this draft that represent an improvement to our current health care system, but it does not appear this draft as written will accomplish the most important promise that we made to Americans: to repeal Obamacare and lower their health care costs." (Joint paper statement on 6/22)

Lee and Johnson are both asking for states to have more flexibility in designing their own health care systems. While they came out against the current version of the bill Thursday, a Lee statement Friday night and a Johnson op-ed published Monday morning had more specific requests.

Still reviewing but has concerns: 3

Sen. Susan Collins (Maine) -- "Senator Collins will carefully review the text of the Senate health care bill this week and into the weekend.  She has a number of concerns and will be particularly interested in examining the forthcoming CBO analysis on the impact on insurance coverage, the effect on insurance premiums, and the changes in the Medicaid program." (Paper statement on 6/22)

"It makes no sense to single out Planned Parenthood from all the Medicaid providers...there's already a ban against using federal funds for abortion so there's absolutely no need for that." (To reporters on 6/22)

Sen. Rob Portman (Ohio) -- "There are some promising changes to reduce premiums in the individual insurance market, but I continue to have real concerns about the Medicaid policies in this bill, especially those that impact drug treatment at a time when Ohio is facing an opioid epidemic. I look forward to examining this new proposal carefully and reviewing the analysis by the Congressional Budget Office when it is available. If the final legislation is good for Ohio, I will support it. If not, I will oppose it. As this process moves forward, I will continue to work to protect Ohio's interests and ensure that our health care system works better for all Ohioans." (Paper statement on 6/22)

Sen. Mike Rounds (South Dakota) -- Rounds said there were some "good parts" to the bill but there needs to be more work done on group markets. (To reporters on 6/22)

He said he wasn't happy with this process but thought one week was enough time to review the bill for a vote. (To reporters on 6/22)

Sen. Marco Rubio (Florida) -- "Senator Rubio will decide how to vote on health care on the basis of how it impacts Florida.
