(CNN) President Obama had some explaining to do Tuesday night during a reception at the White House.
He was attending the Asian American and Pacific Islander Heritage Month event when he wound up with a lipstick smudge on his collar.
The President didn't want anyone, including the First Lady, to get the wrong idea, so he decided to explain how he got it.
"I want to thank everybody who's here. The incredible warmth of the reception. A sign of the warmth is the lipstick on my collar. I have to say, I think I know the culprit. Where is Jessica Sanchez? Jessica - It wasn't Jessica, it was her aunt. Where is she? Auntie, right there -- look at this. Look at this. I just want everybody to witness. So, I do not want to be in trouble with Michelle. That's why I'm calling you out. in front of everybody."
During his speech, the president also discussed some serious topics, including the need for immigration reform in the US.
