BLADENSBURG, Md. (AP) — The American Legion is seeking to intervene in a lawsuit challenging the constitutionality of a cross-shaped World War I memorial in Maryland.

The lawsuit was filed earlier this year by the American Humanist Association, a group that advocates for atheists and others who do not believe in a deity. It says the display of the cross by the Maryland-National Capital Park and Planning Commission amounts to government sponsorship of religion and violates the First Amendment.
