The National Rifle Association has filed an amicus brief on Wednesday supporting the American Civil Liberties Union’s lawsuit challenging the constitutionality of the National Security Agency’s phone records collection program.

The NRA filed a brief of amicus curiae in U.S. District Court in support of the plaintiff in the ACLU’s lawsuit against key Obama administration officials, including director of national intelligence James Clapper, NSA director Keith Alexander, defense secretary Chuck Hagel, Attorney General Eric Holder and FBI director Robert Mueller.

The gun-rights group — often associated in the public consciousness with conservative politics — and the progressive-leaning civil rights advocacy organization might appear to be strange bedfellows, but the NRA claims that the two groups have common interests.
