Barack Obama to miss Muhammad Ali funeral for daughter's graduation

US president Barack Obama is to miss Muhammad Ali's funeral to attend his daughter's graduation.
Mr Obama and wife Michelle will be in Washington for eldest daughter Malia's high school ceremony, the White House confirmed.
Ali's widow Lonnie spoke to Mr Obama over the phone and appreciated his "kind words and condolences," family spokesman Bob Gunnell said.
The Obamas are sending a letter to be read at Friday's service in Louisville, Kentucky, where White House senior adviser Valerie Jarrett - who knew Ali personally - will represent the president.

The president paid a heartfelt tribute to the boxing legend , who he said "shook up the world and the world is better for it".
In a heartfelt tribute Mr Obama revealed he keeps a pair of Ali's gloves in his private study at the White House, and said we are fortunate that "The Greatest chose to grace our time".

He shook up the world, and the world's better for it. Rest in peace, Champ. pic.twitter.com/z1yM3sSLH3
