Brown died Aug. 9 after he was shot during an altercation with St. Louis County police officer Darren Wilson.
The controversial incident, in which some witnesses said the unarmed Brown was holding his hands up and others say he attacked Wilson, led to racial tension and protests about the militarization of police.
Brown's funeral is Monday at the Friendly Temple Missionary Baptist Church. Brown's uncle, the Rev. Charles Ewing, will provide the eulogy.
Civil Rights leader the Rev. Al Sharpton is also expected to speak.
The White House is sending Broderick Johnson, the head of the My Brother's Keeper Task Force, Marlon Marshall, a St. Louis native who attended high school with Brown's mother, and Heather Foster, who works with Marshall in the White House Office of Public Engagement, the Washington Post reported.
"In too many communities, too many young men of color are left behind and seen only as objects of fear," President Obama said, speaking about Brown's death. "And through initiatives like My Brother's Keeper, I'm personally committed to changing both perception and reality. And already, we're making some significant progress, as people of good will of all races are ready to chip in."
Meanwhile, Brown's father, Michael Brown Sr., asked for protests to be halted on the day of his son's funeral.
