The editor-in-chief of The Huffington Post is addressing the American Civil Liberties Union of Michigan at the organization's annual dinner.

Arianna Huffington was to be the keynote speaker at Saturday's dinner at the Westin Book Cadillac hotel in downtown Detroit.

She is the editor-in-chief and a co-founder of the news and opinion Web site. It was founded in 2005.

ACLU of Michigan Executive Director Kary Moss says the dinner will highlight the work of the civil-liberties group over the half-century since its founding in 1959.
