Obama Cracks Birther Joke in Kenya

NAIROBI, Kenya -- While in Kenya Saturday night, President Obama couldn't help but crack a birther joke.

"Some of my critics back home might be suggesting I'm back here to look for my birth certificate," the president said as he delivered a toast at a state dinner at the State House in Nairobi. "That is not the case."

The birther conspiracies, which suggest Obama was not born in the U.S., are on frequent rotation on the president's comedy routine.

"An American won the Boston Marathon for the first time in 30 years, which was inspiring and only fair, since a Kenyan has been president for the last six," the president joked at the White House Correspondent's Association Dinner in 2014.

In 2011, the president tried to quell the conspiracy theories by releasing his "long form" birth certificate. At the time, real estate mogul Donald Trump, who is now at the top of the polls in the Republican presidential primary, was one of the loudest voices leading the conspiracy theorists.

"Today, I'm very proud of myself because I've accomplished what nobody else" was able to do, Trump said the day the president released his birth certificate.

Obama, who is on his fourth trip to his father's homeland, spent nearly three hours at the state dinner, at one point even dancing with a popular English and Swahili group called Sauti Soul.

"In my visits here as a younger man I could have never imagined the hospitality I met here today," he said. "So I feel my given African name, to be truly blessed."
