Barack Obama has opened up about his marriage to Michelle Obama, offering a rare glimpse into their relationship—and admitting he’s still trying to make up for lost time.

The former president, 63, appeared at Hamilton College in New York on Thursday (April 4), where he touched on everything from gun laws to Donald Trump’s sweeping tariffs. But one of the most talked-about moments came when he candidly addressed his relationship with the former First Lady.

“I was in a deep deficit with my wife,” Obama said during a conversation with College President Steven Tepper. “So I have been trying to dig myself out of that hole by doing occasionally fun things.”

The Obamas have been married since 1992 and spent eight years in the White House — years that Barack has previously admitted put a strain on their marriage. Over the years, online rumors have even swirled around their relationship, with some speculating about tension or divorce—claims the couple has never confirmed.

Michelle Obama hasn’t shied away from discussing the ups and downs of their relationship either. On her podcast, she once revealed the one habit of Barack’s that drove her a little crazy: his relaxed attitude about time.
