Berkshire Hathaway CEO Warren Buffett, J.P. Morgan CEO Jamie Dimon and Amazon CEO Jeff Bezos have chosen a CEO for their health-care venture and will likely reveal the name within two weeks, Buffett told CNBC on Thursday. The three announced a partnership in January to tackle rising health-care costs. Buffett said they've picked a leader and are "just tidying up a couple of things." In an interview with CNBC's Becky Quick, Buffett and Dimon praised their incoming leader and acknowledged the daunting task ahead. Health-care experts have expressed skepticism on whether the three, while business icons, could simplify the current system. Many agree there's plenty of costs to cut, but they doubt the companies can do it.

The interesting thing when interviewing job candidates, Buffett said, was they didn't run into one that "didn't think significant improvement was both possible and important." "It isn't like there's anybody out there that's connected with the system that thinks we've already arrived at nirvana, and they know how difficult the job will be to make major changes," Buffett said. "They're all cheering for us to succeed. "A number of them might not have wanted to be the one to help us succeed, ... but nobody disagreed with the mission, the importance of it or the feasibility," Buffett said. "But it's also a very, very tough nut to crack, and it's going to take significant time. We've got the right person." As CNBC has reported, Todd Combs, an investment manager at Berkshire, has been the lead recruiter for the venture, tasked with the tall order of finding a leader who can work across three companies with a combined 1.2 million employees and simultaneously help develop innovative solutions in a multitrillion-dollar industry. In addition, any candidate would have the pressure of the high-profile mission as well as the weight of working under these three business leaders.
