On Sunday, Obama met President Uhuru Kenyatta at State House in Nairobi and opposition leader Raila Odinga at Kempinski hotel.
While welcoming the 44th US President in Kenya Sunday afternoon, President Kenyatta thanked Mr Obama for keeping his promise to visit the country after his service as US president.
Obama is in Kenya to help launch a sports and training center founded by his half-sister, Auma Obama, the Associated Press reported. Auma Obama attended his 2009 inauguration and was a big part of her brother's 2015 visit to Kenya.
Security was tightened at Kisumu International Airport and in K'Ogelo, Siaya, for visits by former US President Barack Obama. Odinga is now working with Kenyatta's government following a tense political standoff that included an invalidated presidential election.
Another issue that has got Kenya's talking is the report in Tanzanian newspapers that Mr Obama and his family spent eight days in the famous Serengeti National Park before travelling to Kenya.
The former American leader is expected among others to launch a youth centre in Siaya County on Monday before heading to South Africa.
"We are upbeat about the coming of the President Barak Obama", said Rasango, who added he is not expecting much in terms of any announcements of aid.
Obama will also deliver the 16th Nelson Mandela Annual Lecture in Johannesburg to mark 100 years since Madiba's birth in 1918.
Obama announced the trip last week on Twitter, writing, "I'm traveling to Africa for the first time since I left office - a continent of wonderful diversity, thriving culture and remarkable stories".
