"I write a gossip column," Walls said. "I wouldn't print something unless I had a reliable source."
Walls's piece centered around the fact that Gore spoke at his daughter Karenna's graduation in 1994 but will not be speaking again at his youngest daughter Sarah's graduation this year.
"If Harvard really wanted to, they could break their own rules," said Walls, implying that Gore might be allowed to speak at Commencement twice.
Walls' Gore piece ran beneath an item entitled "PamWatch: Actress Out of Control" about Pamela Anderson Lee's behavior at a Kentucky Derby party.
MSNBC has not had a stellar track record in reporting on Harvard so far this year.
"That's the same organization that announced that Hillary Clinton was a candidate for Harvard's presidency,” said Joe Wrinn, University spokesperson.
