President Obama had dinner with his African relatives at Nairobi's Villa Rosa Kempinski Hotel on Friday night.

Obama arrived in Kenya earlier in the day to begin a five-day trip that includes a visit Ethiopia, delivering a speech before the African Union and attending the annual Global Entrepreneurship Summit in Nairobi.

Obama has traveled to his father's homeland of Kenya before, most recently when he was a senator.

Approximately three-dozen members of his father's extended family were in attendance Friday night, according to reports from the small pool of reporters traveling with Obama. He sat in between his step-grandmother, Mama Sarah, whom he reportedly calls "Granny," and his half-sister, Auma Obama.

His arrival in Kenya marks his fourth trip to sub-Saharan Africa, the most of any sitting president.

Obama wrote extensively about Kenya and the role it played in shaping him in his memoir, Dreams From My Father.

Before his departure, the White House offered few details about what personal time Obama, traveling without First Lady Michelle Obama or daughters Malia and Sasha, would spend with the extended Obama clan.

A large, bipartisan congressional delegation accompanied Obama on Air Force One. Members traveling with him were Sens. Chris Coons, D-Del., Jeff Flake, R-Ariz., and Ed Markey, D-Mass. From the House, Reps. Karen Bass, D-Calif., G.K. Butterfield, D-N.C., Eddie Bernice Johnson, D-Texas, Barbara Lee, D-Calif., Gregory Meeks, D-N.Y., Charlie Rangel, D-N.Y., and Terri Sewell, D-Ala. were also on the trip.

Another 10 lawmakers, all Democrats and all members of the Congressional Black Caucus, flew on a separate military plane because there wasn't enough room aboard Air Force One. They will reportedly fly with Obama on the return flight Tuesday.

Those members are Reps. Emanuel Cleaver of Missouri, John Conyers of Michigan, Marcia Fudge of Ohio, Al Green of Texas, Sheila Jackson Lee of Texas, Robin Kelly of Illinois, Gwen Moore of Wisconsin, Donald Payne Jr. of New Jersey, Cedric Richmond of Louisiana and Bennie Thompson of Mississippi.
