Former President Barack Obama cracked a joke at President Joe Biden before delivering remarks at the White House on Tuesday.
"Vice President Biden," Obama said as he acknowledged Biden during his speech, drawing laughter from the audience.
Biden laughed along and embraced the former president, whom he served as vice president during both Obama's terms.
"It is good to be back in the White House," Obama added. "It's been a while — I confess, I heard some changes have been made by the current president since I was last here."
He added: "Apparently, Secret Service agents have to wear Aviator glasses now. The Navy mess has been replaced by a Baskin-Robbins. And there's a cat running around."
Obama, Biden, and Kamala Harris convened to promote the expansion of the 2010 health care reform legislation Affordable Care Act.
Biden said it felt like the "good old days" during the event.
"My name is Joe Biden and I'm Barack Obama's vice president," Biden added.
