Civil rights activists regarded the construction of the arch as a token of racial discrimination. On July 14, 1964, during the workers' lunchtime, civil rights protesters Percy Green and Richard Daly, both members of
Congress of Racial Equality, climbed 125 feet up the north leg of the arch to "expose the fact that federal funds were being used to build a national monument that was racially discriminating against black contractors and skilled black workers." As the pair disregarded demands to get off, protesters on the ground demanded that at least 10% of the skilled jobs belong to African Americans. Four hours later, Green and Daly dismounted from the arch to charges of "trespassing, peace disturbance, and resisting arrest."

inter alia spurred the
United States Department of Justice to file the first
pattern or practice case against AFLāCIO under
Title VII of the Civil Rights Act of 1964, on February 4, 1966, but the department later called off the charges.
