Jimmy Carter and Al Gore are planning to call for Hillary Clinton to end her presidential run, according to an article published Sunday in a Scottish newspaper.

The Scotsman -- the same paper that quoted Barack Obama adviser Samantha Power calling Clinton a "monster," which resulted in her dismissal from the campaign -- reported that the two politicians are teaming up because they believe it is in their party's best interest to end the prolonged battle for the Democratic presidential nomination and unite behind Obama, who continues to maintain a lead over Clinton in number of pledged delegates.

"They're in discussions," a source close to Carter reportedly told the newspaper. "Carter has been talking to Gore. They will act, possibly together, or in sequence."

According to the report, the two party elders will either meet with Clinton privately to urge that she withdraw her candidacy or they will publicly endorse Obama in the hopes that more superdelegates will follow suit.

Clinton still holds a lead over Obama in number of superdelegates. It is not known when Carter and Gore will make such an appeal to Clinton, but insiders say it is certain to happen, the newspaper reported. It added that both pols have clashed with the Clintons in the past.

In an interview that aired Sunday on ABC News' "This Week," Carter said he will not endorse a candidate until the Democratic convention in August.

"The only thing I know is that, I have not made an endorsement, and don't intend to, until the time of the convention, but so far as I know, all my children and grandchildren are supporting Obama," Carter said. "I got permission, by the way, from my children and grandchildren, and their spouses, to reveal their intention. I haven't yet revealed what my intention is directly, or my wife."

The former president also said that superdelegates should be free to endorse whomever they feel is best able to lead -- regardless of the popular choice in the caucuses and primary contests.

"Any superdelegate who wishes to deviate from that opinion should be perfectly free to do so," Carter said. "My hometown, my county, my state went overwhelmingly for Obama. But if I decided later on to support Mrs. Clinton, I would feel free to do so."

Clinton has insisted on numerous occasions that she intends to remain in the primary race until the convention. Her campaign laughed off the report on Sunday, noting the one unnamed source for the story.

Clinton campaign spokesman Mo Elleithee would not respond to the report, but repeated a common refrain from the campaign.

"This is an incredibly close race and there are still millions of voters who haven't cast ballots yet. We think every voter should have a chance to have their voice heard," he said.
