In a Facebook comment on the video posted by the girl's grandmother, Caprina Harris, the president told the young girl, who shares a birthday with Obama, that once he left office, he wasn't going anywhere.
"Caprina, tell her to dry her tears, because I'm not going anywhere. Once I leave the White House, I'll still be a citizen just like her," Obama wrote. "And when she grows up, she can get involved right alongside me. In the meantime, I'll keep an eye out for her letter, and we'll always get to celebrate our birthdays together!"
