Washington (CNN) – Sen. John Kerry, who tapped former Sen. John Edwards for the No. 2 spot on the 2004 Democratic presidential ticket, said Wednesday that he was "disappointed" by Edwards' political and personal downfall in the wake of revelations about an extra-marital affair and Edwards' recent admission that he fathered a child out of wedlock with his former mistress.
"Honestly, it's a tragedy," the Massachusetts Democrat said in an interview that will air on CNN's Larry King Live.
Kerry said he was shocked "and obviously disappointed."
"I think everybody just feels awful about it," Kerry continued, "in terms of their family, their relationship that everybody saw publicly, the promise, the hope, you know, obviously a capable career."
In the interview, Kerry also said that he has spoken to John Edwards' wife, Elizabeth, a number of times including very recently.
But, Kerry said he has not spoken to his former running mate.
"I have not. I have called their home, but I didn't know who would answer. I certainly was ready and willing and hoping to say a word [to John Edwards]," he said.
Kerry sat down with his wife, Teresa Heinz-Kerry, and CNN's Larry King in the couple's first joint interview since Mrs. Kerry announced she has breast cancer, a diagnosis she shares with Elizabeth Edwards.
The senior senator from Massachusetts also disussed the Republican victory in last month's special election to replace the late Sen. Edward Kennedy, who represented
Massachusetts in the Senate for more than four decades.
Bucking the political conventional wisdom, Kerry called Scott Brown's win "very understandable."
"If you were up in Massachusetts as I was, you can feel the anger and the frustration that people have with Washington, with what's not happening here," the longtime senator said.
"Scott brown tapped into that," Kerry also said. "He presented a refreshing alternative in that regard and I think all of us need to respect that part of it. Now I wouldn't over-interpret what happened. It was still a close race. And if certain things had happened campaign-wise, maybe it would have been a different outcome."
