Protecting migrants and honoring the humanity of those who died on the perilous trail is a kind of religion in southern Arizona where spiritual leaders four decades ago founded the Sanctuary Movement, a campaign to shelter Central Americans fleeing civil war, and scores of volunteers carry on their legacy today. Faith-based groups working in migrant activism run the gamut from the Tucson Samaritans, which leaves lifesaving caches of water, food and other provisions in the remote wilderness, to Catholic Community Services of Southern Arizona, which operates a shelter, to Methodists providing asylum-seeking families with legal aid and a place to stay, to name a few.

A border wall. Smugglers. Small children being dropped into America in the darkness. A grainy video released Wednesday by authorities — its figures visible only in ghostly white outline, its stark storyline dramatic and obvious — captures, in mere seconds, the dangers for migrant children at the southern U.S. border.

A North Dakota construction company favored by President Donald Trump has received the largest contract to date to build a section of Trump’s signature wall along the U.S.-Mexico border. Republican U.S. Sen. Kevin Cramer of North Dakota confirmed the $1.3 billion contract for building the 42-mile section of wall through “really tough terrain in the mountains” in Arizona. That's about $30 million per mile.
