The cause of the Michelle Obama eye roll may forever be a mystery.
House Speaker John Boehner says he has no idea why the First Lady looked visibly annoyed and rolled her eyes at him during an inaugural lunch Monday.
During a meeting of House Republicans on Capitol Hill Tuesday, Boehner addressed the caught-on-tape interaction, saying he has "no clue" what he said.
"He said, 'I have no clue what that was about," Louisiana Republican Rep. John Fleming told reporters. "He said they were just having a casual conversation."
"He said he doesn't know why she rolled her eyes."
"It was nothing they were communicating about that would be a reason to do that so he's not sure. He said that maybe she heard something else."
"Maybe there was another conversation she heard, or was having."
Boehner was sitting next to the First Couple at a lunch after President Obama's inaugural address when he turned to them and said something.
Moments later, something made the First Lady roll her eyes. Given the strained relationship between Obama and Boehner, many were quick to jump on Michelle.
The exchange was caught on tape but cameras did not pick up the audio. Thus, this critical moment of U.S. history will forever remain a mystery.
UPDATE: Expert lip reader Larry Wenig tells Inside Edition that - he believes - John Boehner was asking President Obama if he wanted to join him for a cigarette before lunch.
Wenig believes Boehner - a known smoker - then tapped the FLOTUS on the arm before joking to the president that “somebody won’t let you do it,” referring to Michelle Obama.
