Barack Obama joked he was "born in Kenya' on stage at his foundation's first conference, in reference to "birther" conspiracy theories that he was ineligible to become the 44th president of the United States.

The former president was hosting the Obama Foundation's first global summit in Chicago when he made the joke, which appeared to be a swipe at current President Donald Trump who was a high profile promoter of the "birther" conspiracy theory.

"The reason I’m so excited to see you all here today in part is because this is where I started,” he told the audience.
