White House senior adviser Valerie Jarrett will represent President Obama, who's attending his daughter's high school graduation.
Today's memorial follows a traditional Muslim prayer service that was held for Ali yesterday.
More than 14,000 people attended including Jesse Jackson, Louis Farrakhan, and boxing promoter Don King.
