Protesters will get public sites for demonstrations during Republican Donald Trump¡¯s presidential inauguration, a major federal land agency said on Thursday, after being threatened with a lawsuit from civil rights lawyers who accused it of quashing dissent.

Up to 900,000 people are expected to pack into the U.S. capital for the New York businessman¡¯s Jan. 20 swearing-in to his first political office. Some plan to protest Trump¡¯s more controversial promises, including plans to build a wall along the Mexican border and deport illegal immigrants.

Only three of the more than 30 groups seeking to stage rallies either protesting or celebrating Trump¡¯s election independently of the Trump Presidential Inaugural Committee have received permits to use National Park Service land before, during or after Trump¡¯s inauguration.
