In January 2017, Clay argued with Republican lawmakers over the right to hang a controversial painting in the Capitol. The winner of an art competition, the painting represents the violent Ferguson unrest of 2014 and ensuing police-community relations in Ferguson, Missouri, depicting police officers as pigs while apprehending suspects. The painting is displayed near the police security checkpoint. Representative Duncan D. Hunter removed the painting and Clay rehung it. Several Republicans, including Doug Lamborn, Dana Rohrabacher, and Brian Babin, repeatedly removed the painting, and Clay rehung it each time. Clay then attempted to file a complaint with the Capitol Police accusing Hunter of theft. After the architect of the U.S. Capitol ruled that the winning painting had violated the rules of the art competition and ordered its permanent removal, Clay sued to overturn the decision, but his suit was dismissed by a federal judge. Clay continued to assert a First Amendment argument on behalf of his young constituent, asking, "How is it possible that we stand for freedom of speech and freedom of expression every place across this country, except the U.S. Capitol?"
