Sen. Bernie Sanders said Sunday he is getting ready to introduce single-payer healthcare legislation following Senate Republicans' failure to repeal and replace Obamacare.

"Absolutely. Of course we are, we're tweaking the final points of the bill and we're figuring out how we can mount a national campaign to bring people together," the Vermont independent told Jake Tapper on CNN's "State of the Union."

Sanders has long called for a "Medicare For All" approach to healthcare, including during his failed Democratic presidential nomination campaign last year.

Earlier this month, Sanders told Tapper he would introducing the proposal following the conclusion of the Senate debate on Obamacare.

It is unclear when Sanders will introduce this legislation. The Senate has only two weeks left in session before the August recess.

Sen. Steve Daines, R-Mont., introduced a single-payer healthcare system amendment earlier this week, though that failed. Sanders called that proposal a "sham" amendment.
