While some may have challenged his political agenda, or the legacy he leaves behind, very few have questioned President Obama’s commitment to his, and the nation’s, first lady.
Theirs is a love story that even the president’s staunchest opponents wouldn't dare dispute.
They tied the knot on October 3, 1992. Years later, Michelle took on a role she didn’t ask for, according to her husband, but embraced it anyway “with grace and with grit and with style and good humor.”
The first lady has demonstrated that wit in ways that make us smile — and swoon.
“Roses are red, violets are blue. You are the president and I am your boo,” she told him last year in a videotaped message during President Obama’s visit to the Ellen Degeneres Show on Valentine’s Day.

But most of the time, their love for each other is shown in more subtle, yet very sweet and always sincere, ways.
In celebration of the first lady's 53rd birthday Tuesday, and her husband's sweet tweet to her, we offer a look back at some of our favorite moments between POTUS and FLOTUS through their White House years.
Inaugural Ball
Jan. 20, 2009: Hours after being sworn in, President and Michelle Obama made appearances at numerous Inaugural Balls. On their way to one of them, inside a chilly freight elevator, the president removed his tuxedo jacket and placed it over his wife's shoulders — and the now-legendary gown by Jason Wu.
"Then they had a semi-private moment as staff members and Secret Service agents tried not to look," White House photographer Pete Souza recalled.
Romance in the Red Room

Behind the podium

Roaring and gnashing
March 28, 2016: Two annual traditions at the White House involving young children have provided ample opportunities for the Obamas to show their sweet and silly sides. Every spring, the first couple read stories to a rapt audience of kids (and their parents) at the Easter Egg Roll on the South Lawn. Then, in the fall....
Halloween fun
