Tulsi Gabbard of Hawaii is welcoming the movement of the North Korea Sanctions Enforcement Act, which passed the U.S. House of Representatives Tuesday by a stunning 418 to 2.

The bill, introduced by Ed Royce, a Republican from California, has 36 co-sponsors, including Gabbard, a Democrat.

Mark Takai of Hawaii, a fellow Democrat, also voted in favor of the bill.

The measure’s passage comes just days after North Korea tested what it says is its first hydrogen bomb — something nuclear weapons experts doubt about.

Still, the matter is being taken seriously. Speaking on the House floor in support of the bill Monday, Gabbard said:

“North Korea continues to pose a serious and dangerous threat to my constituents in Hawaii, the Pacific, and the West Coast of the United States. Our communities and our families lie within range of North Korea’s intercontinental ballistic missiles. North Korea’s nuclear tests just a week ago, and their continued pursuit of developing more nuclear weapons and miniaturizing those weapons, serve as a reminder of the threat that North Korea poses to our country, which my constituents in Hawaii  know all too well.”

The sanctions act now heads to the Senate.
