To avoid a possible repeat of the President Bill Clinton and Monica Lewinsky episode, US President Barack Obama yesterday night took time to explain the lipstick stain on his collar.

Obama who was speaking at at a White House reception for Asian American and Pacific Islander (AAPI) Heritage Month in the East Room said the stain is “a sign of that warmth” with which he was received.

“I have to say I think I know the culprit,” he said, adding it was the aunt of ‘American Idol’ runner-up Jessica Sanchez.

“Auntie, right there, look at this,” he said, pointing to the smooch mark as the crowd laughed and cheered.

“I just want everybody to witness. I do not want to be in trouble with Michelle. That’s why I am calling you out right in front of everybody.”
