The Washington Post reports that Barack Obama called Nancy Reagan to apologize for joking that he wouldn't be holding any seances like the former first lady did:
"President-elect Barack Obama called Nancy Reagan today to apologize for the careless and off-handed remark he made during today's press conference," transition spokeswoman Stephanie Cutter announced. "The President-elect expressed his admiration and affection for Mrs. Reagan that so many Americans share and they had a warm conversation."
I'm sure Nancy Reagan was too polite to point this out, but she, in fact, never held a seance-- Mary Todd Lincoln did.
