US President Barack Obama

US President Barack Obama praised Nigerian President Goodluck Jonathan on Wednesday for conceding defeat in an election that he said showed "Nigeria's commitment to democratic principles."
"President Jonathan has placed his country's interests first by conceding the election and congratulating president-elect (Muhammadu) Buhari on his victory," Obama said in a White House statement. Buhari will oversee the first democratic change of power in Africa's most populous nation.
