Michelle Obama will travel to Liberia, Morocco and Spain later this month to speak to girls and young women about the importance of education and promote the federal government’s work to help girls stay in school. Obama’s daughters, Malia and Sasha, and her mother, Marian Robinson, will join her.

The trip, which will begin June 27 and end July 1, is part of the White House’s Let Girls Learn initiative and the latest in a series of overseas goodwill tours Obama has made.

In Liberia, the first lady will visit a Peace Corps training facility and meet with girls at a leadership camp. She will also meet with Liberian President Ellen Johnson Sirleaf, the first woman elected to lead an African nation.

The following day, Obama will make a two-day swing through Morocco, where she will be joined by actresses Meryl Streep and Freida Pinto, who are advocates for issues affecting women and girls. There, the first lady will participate in a panel discussion with the stars, moderated by CNN’s Isha Sesay, about the educational challenges girls face in the region.

On the final leg of the trip, Obama will deliver a speech in Madrid and meet with the queen of Spain, Letizia Ortiz Rocasolano.

The White House said in a statement that the first lady will announce new commitments by organizations to support Let Girls Learn, which was launched to help the 62 million girls around the world who are not enrolled in school.
