WASHINGTON – Former first lady Michelle Obama said Thursday that ex-President George W. Bush has become her "partner in crime" after years of sitting together at official events.

"President Bush and I are forever seatmates because of protocol – that's how we sit at all the official functions," Obama said on NBC's "Today" show. "So he is my partner in crime at every major thing where all the formers gather."

"I love him to death," Obama added. "He's a wonderful man. He's a funny man."

Obama expressed her affection for Bush after being asked about the moment when Bush handed her a cough drop at the Sept. 1 funeral of the late Arizona Republican Sen. John McCain. The moment, which happened at the National Cathedral in Washington, went viral on social media.

Bush was handing a cough drop to his wife, Laura, when Obama leaned over and asked him if she could have one too. She said she didn't realize that anyone was watching the "simple gesture."

"And I will add that they were old cough drops," Obama said, describing them as being in an official White House box. "And I was like, 'How long have you had these?' They said, 'A long time. We got a lot of these.' "

Obama, a Democrat, said her friendship with Bush, a Republican, defies labels.

"Party doesn't separate us," she said. "Color, gender, those sort of things don't separate us."
