Wolfson made the explosive charge in an interview with Politico after suggesting as much in a conference call with reporters.
On the call, Wolfson said: “Sen. Obama is running on the strength of his rhetoric and the strength of his promises and, as we have seen in the last couple of days, he’s breaking his promises and his rhetoric isn’t his own.”
“When an author plagiarizes from another author there is damage done to two different parties. One is to the person he plagiarized from. The other is to the reader,” said Wolfson.
Obama closely echoed a passage from a speech that Deval Patrick, now the Massachusetts governor, used at a campaign rally when he was running for that office in 2006.
