President Barack Obama on Tuesday dedicated a national monument on Capitol Hill in honor of the people who have fought for women’s rights, calling the building a “centerpiece for the struggle for equality.” Obama’s remarks at the historic Sewall-Belmont House and Museum—which will now be called the Belmont-Paul Women’s Equality National Monument—came on Equal Pay Day, which recognizes the wage gap that persists between men and women in the work force. “I want young girls and boys to come here, 10, 20, 100 years from now, to know that women fought for equality, it was not just given to them,” Obama said, the Washington Post reported.
