Sen. Ron Johnson, R-Wis., said it is unlikely he will be prepared to vote on a GOP healthcare plan next week.
"What I've told leadership very clearly is I'm going to need time and my constituents are going to need time to evaluate exactly how this is going to affect them, so I personally think that holding a vote on this next week would definitely be rushed," Johnson told CNN's "New Day" program on Wednesday.
"I can't imagine, quite honestly, that I'd have the information to evaluate and justify a yes vote within just a week."
A discussion draft of a bill is expected to be released Thursday by Senate Majority Leader Mitch McConnell, R-Ky., The Hill said, and a vote is expected to come as early as next week.
"I've told (McConnell), unless I have the input from my constituents, unless I have got the information I need to justify a yes vote, I won't be voting yes," Johnson said
And he added: "I want to fully vet it in the public. I want to make sure that my constituents have enough time to provide input. I am not going to criticize the process unless we start taking a vote way too early."
