Supreme Court Justice Samuel Alito faced backlash Tuesday for joking about a child in a Ku Klux Klan robe visiting a black Santa during arguments in a high-profile free speech case.

The justices were weighing the case of aChristian graphic designer from Colorado who objects to designing wedding websites for same-sex couples when Alito proposed a hypothetical scenario, asking whether a black person dressed as Santa could refuse to take a picture with a child dressed in a KKK robe.
