President Barack Obama is commemorating the 60th anniversary of the Supreme Court’s landmark Brown vs. Board of Education school desegregation decision by meeting with families of the plaintiffs in the case as well as the lead attorneys and the NAACP Legal Defense Fund.

Obama will host the group, including lawyers Jack Greenberg and William Coleman, in the White House East Room Friday afternoon. Greenberg argued the case; Coleman was a leading legal strategist in the case.

First lady Michelle Obama was observing the anniversary by traveling Friday to Topeka, Kan., site of the lawsuit that initiated the case. The first lady was to meet with high school students in a college preparatory program and later was speaking at a pre-graduation event for seniors in the Topeka Public School District.
