From Obama's speech:
So we hope everybody has a great time. We are incredibly grateful for your service, and we're thankful that you get a chance to spend the Fourth here with us. And by the way, it's Malia's birthday, so she is appreciative that you're all going to be wishing her happy birthday as well. Very clever of the Obamas. Manifest a daughter out of thin air (where are the pregnancy photos?) and arrange for her birth certificate to say the 4th of July. Do you think the cabal has political plans for Malia?
