Former president Barack Obama went back to the White House on Tuesday and cracked some jokes. The 44th president, who returned to his old home to commemorate the 12th anniversary of the signing of the Affordable Care Act, took a friendly jab at President Joe Biden.

Shortly before embracing his former running mate, Obama jokingly referred to Biden as “vice president.”

“That was a joke,” the former president said after showing some of his usual humor. “That was all set up. My president, Joe Biden.Vice President Harris.”

Obama had a few more jokes to launch during his vsiit.

“I heard some changes have been made by the current president since I was last here,” he said, Deadline reports. “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 The Navy mess has been replaced by a Baskin Robbins.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. I guarantee you Bo and Sunny would have been very unhappy about.”

Speaking about the Affordable Health Care Act, Obama said he “intended to get health care passed even if it cost me re-election, which looked for a while like it might.”

“The ACA was an example of why you run for office in the first place,” he said. “We are not supposed to do this just to occupy a seat or hang on to power. We are supposed to do this because it is making a difference in the lives of the people who sent us here.”

Biden came back with his own humor when spoke on Tuesday.

“My name is Joe Biden and I’m Barack Obama’s vice president.” He said. “Welcome back to the White House, man. It feels like the good old days.”

Vice President Harris raved about the Affordable Health Care Act when she took the podium.

“On March 23, 2010, the Affordable Care Act was signed into law,” Harris said. “In the 12 years since, the ACA has delivered high-quality, affordable health care to more than 30 million Americans. Those Americans are working parents and young children, college students and older Americans. Millions of people who have never been able to afford coverage before.”
