President Obama has wrapped up his historic visit to Kenya and Ethiopia with an address to the African Union. In his speech, Obama called on the continent’s long-entrenched leaders to step aside, saying, “Nobody should be president for life.” The address marked the first time a U.S. sitting president has spoken before African Union. Obama joked that he could win a third term — but can’t run.

President Obama: “I actually think I’m a pretty good president. I think if I ran, I could win. But I can’t. So there’s a lot that I’d like to do to keep America moving, but the law is the law.”

Obama’s comments come just days after Burundi’s president won re-election for a third term, despite massive protests denouncing the move as unconstitutional.
