Officials have ordered a privately funded section of wall on the U.S.-Mexico border to keep its gate open indefinitely, saying organizers failed to obtain required permits, according to BuzzFeed News.

The International Boundary and Water Commission (IBWC), which oversees waterway issues between the U.S. and Mexico, said the organizers of We Build the Wall, which raised more than $23 million, had not obtained permission to build on federal land.

The half-mile barrier, on the border near Sunland Park, N.M., restricts access to a public monument and waterways, according to the IBWC.
