Border wall work begins on sacred Tohono O'odham land in Arizona

Construction has begun on a 30-foot border wall segment in Arizona as part of a $46 billion effort to fortify the southern border, despite opposition from the Tohono O'odham Nation which says the work trespasses on sacred land and has sued the federal government; CBP says the desert corridor is a major smuggling route and the project is designed to close it, while a federal judge noted the work would occur within the Roosevelt Reservation buffer zone and contractors have begun soil sampling at several sites amid tribal protests.
