NEW YORK (AP) -- The Ku Klux Klan has rebounded by exploiting current hot-button issues, especially immigration, according to a new report released by the Anti-Defamation League.

The Klan, and other white supremacist groups like skinheads and neo-Nazis, grew significantly more active in the past year, holding more rallies, distributing leaflets and increasing their presence on the Internet -- much of it focused on stirring anti-immigrant sentiment, according to the report.
