Congressman intends to sue over removal of painting

The painting, which shows a pig in a police uniform, divided members of Congress for its depiction of Ferguson, Missouri, where weeks of protests occurred after the police shooting of an unarmed black man.

"Congressman Clay is seeking an appropriate remedy through this federal litigation and he is proud to defend both the fundamental rights of his constituent and the First Amendment," according to an advisory his office sent in advance of a press conference Clay intends to hold Tuesday outside the U.S. District Court for the District of Columbia.
