Carter told Britain’s Sky News that Clinton “had a perfect right” to keep running – but that “a lot of the superdelegates will make a decision quite, announced quite rapidly, after the final primary on June 3," he told Sky News Sunday.
"I have not yet announced publicly, but I think at that point it will be time for her to give it up," he added.
Carter, a superdelegate, has not made endorsement but has spoken out frequently in favor of Barack Obama.
Obama leads Clinton among superdelegates and has captured the majority of pledged delegates up for grabs this primary season.
