Input: Bush as president occasionally phoned Clinton
 George W. Bush had a special phone friend during his White House years: Bill Clinton.
 Asked on CBS television's "Face the Nation" whether it was true that he often called Clinton  Bush replied: "I don't know about often  but I did. I called him. He didn't call me because he knows how busy a president is. I called him and we chatted on occasion."
 "I was always pleased when he called me " Clinton said as he sat beside Bush for the interview. "I make it a practice never to bother the president. I don't call President Obama either. ... They got plenty to do."
Neither Republican Bush nor Democrat Clinton said just what they discussed.

 Bush's eight years in office followed Clinton's two terms. While poles apart politically  the ex-presidents said they consider themselves to be friends.
 "We have developed a very honest  good friendship " Clinton said. "And we've made our disagreements respectful and we've had a good time doing it."
