x-point- a racist in the White House?
It has already happened
Woodrow Wilson-from Wikipedia:
While president of Princeton University, Wilson discouraged blacks from even applying for admission.[36] Princeton would not admit its first black student until the 1940s.
Wilson allowed many of his cabinet officials to establish official segregation in most federal government offices, in some departments for the first time since 1863. "His administration imposed full racial segregation in Washington and hounded from office considerable numbers of black federal employees."[37] Wilson and his cabinet members fired many black Republican office holders, but also appointed a few black Democrats. W.E.B. DuBois, a leader of the NAACP, campaigned for Wilson and in 1918 was offered an Army commission in charge of dealing with race relations. (DuBois accepted but failed his Army physical and did not serve.)[38] When a delegation of blacks protested his discriminatory actions, Wilson told them that "segregation is not a humiliation but a benefit, and ought to be so regarded by you gentlemen." In 1914, he told the New York Times that "If the colored people made a mistake in voting for me, they ought to correct it."
