President Barack Obama attended the wedding of vice presidential debate moderator Martha Raddatz in 1991, the Daily Caller reported.
ABC News confirmed that Obama -- then a law school classmate of groom Julius Genachowski and a colleague of his at the Harvard Law Review -- was a guest, but called any implication of a conflict of interest for Raddatz in Thursday's debate "absurd." Raddatz is ABC's senior foreign affairs correspondent.
"[Obama] attended their wedding over two decades ago along with nearly the entire Law Review, many of whom went on to successful careers including some in the Bush administration," ABC News spokesman David Ford said in a statement.
Raddatz and Genachowski divorced in 1997 and are each remarried. Obama nominated Genachowski to be chairman of the Federal Communications Commission in 2009.
ABC began pushing back against the Daily Caller on Tuesday, before the site's story was even published early Wednesday. Politico, the Daily Beast and the Huffington Post all published items about the Caller's planned story. Daily Beast columnist Andrew Sullivan said the site was "hard at work trying to smear ABC News' moderator Martha Raddatz because her second husband - are you sitting down? - once worked with Barack Obama on the Harvard Law Review. I know: deeply shocking. ... They're now trying to find out if Obama attended his Law Review friend's wedding."
ABC's full statement:
"Martha Raddatz is known for her tough, fair reporting, which is why it was no surprise to her colleagues inside and outside ABC News that she was chosen by the Commission on Presidential Debates for this assignment. Barack Obama was a law school classmate of Raddatz's ex-husband Julius Genachowski at Harvard. At the time Barack Obama was a student and president of the Law Review. He attended their wedding over two decades ago along with nearly the entire Law Review, many of whom went on to successful careers including some in the Bush administration. Raddatz and Mr. Genachowski divorced in 1997 and both are now remarried."
In August, the Daily Caller highlighted Raddatz's tie to the White House over Genachowski and Obama's work together on the Harvard Law Review and Genachowski's appointment to the FCC.
Thursday's debate is the one and only time Vice President Joe Biden and Republican vice presidential nominee Paul Ryan will face off against one another.
