TOPEKA, Kan. (AP) — First lady Michelle Obama has met with a small group of Kansas high school students ahead of an evening speech at a ceremony honoring graduating seniors. Obama met Friday with 11 students at the national park site in Topeka dedicated to the Brown v. Board of Education decision by the U.S. Supreme Court that declared segregated schools unconstitutional. Her visit took place the day before the 60th anniversary of the decision. The Brown site is in a former all-black elementary school. The afternoon meeting involved sophomores and juniors participating in a federally funded program helping at-risk kids prepare for higher education. Obama told them, "It's just going to be essential for you guys to succeed."
