Because of laws restricting fishing, some residents of the Northwest Angle suggested leaving the United States and joining Canada in 1997. The following year, then-U.S. representative Collin Peterson of Minnesota proposed legislation to allow the residents of the Northwest Angle, which was part of his district, to vote on seceding from the United States and joining Canada. This angered the leaders of Red Lake Indian Reservation, which holds most of the Northwest Angle's land. The incident resulted in fishing regulations being better synchronized across these waters.
