Warren Buffett says he spoke with Bill Gates three weeks ago

Warren Buffett told CNBC's Becky Quick that he and Bill Gates remain in contact and recently spent several hours together in Omaha.

“He came by Omaha three weeks ago. I kind of lose track of time, but certainly not three months, and we spent three hours talking together,” Buffett said. “He intends to call me... He already proposed another meeting.”
