President Obama, First Lady Exchange Valentine's Day Wishes on 'Ellen'

Obama is the first sitting president to appear in-studio on DeGeneres' show.

This time around, Obama, becoming the first president to join DeGeneres for an in-studio interview, was more restrained.

"Roses are red, violets are blue, you are the president, and I am your glue," she said, asking him to bring her some chocolate back from California.

Obama responded with his own message from the Los Angeles studio, where he promised he would be gifting the first lady some zucchini bread and a massage.

"Somebody call the Situation Room because things are about to get hot," he replied, over romantic background music. "Michelle, this Valentine's Day, I'm going to treat you right."

Obama, who spent the day in California keynoting several Democratic fundraisers, admitted to DeGeneres his joy with being outside the Washington bubble.

Obama insisted, as he has multiple times during the 2016 presidential campaign, that despite early turbulence, "the ship will be righted" and cooler heads will prevail.
