Captioning the post, Michelle wrote a heartfelt message to her husband. "Happy Father’s Day to all of the amazing dads out there — and to this guy in particular," she said. "@BarackObama, thank you for being such a loving, caring, and attentive dad to our two beautiful girls. We love you so much! 💕"
