ROMA, Texas – As darkness sets on the Rio Grande, U.S. Border Patrol agents hear pumps inflating rafts across the river in Mexico. More than 16,000 unaccompanied children were in government custody as of Thursday, including about 5,000 in substandard Customs and Border Protection facilities. Unaccompanied children are supposed to be held by CBP no more than 72 hours, but they are often held longer because U.S. Health and Human Services lacks space. A group of Republican senators on Friday visited the Rio Grande Valley, which is the busiest corridor for illegal crossings, and toured a holding facility. CBP reported that it took 681 unaccompanied children into custody Wednesday, a total that excludes Mexicans, who are typically returned immediately.

Officials said Customs and Border Protection will use its authority to block products suspected of being produced with forced labor to keep out cotton, tomatoes and related products from the Xinjiang region of northwest China. That is especially true with Chinese cotton that is used to make clothing for export in other countries such as Bangladesh and Vietnam. The U.S. imported about $9 billion worth of cotton goods from China overall last year, according to Brenda Smith, the executive assistant commissioner at Customs and Border Protection's Office of Trade. China denies allegations of rights abuses and forced labor, saying it aims only to promote economic and social development in the region and stamp out radicalism. "The so-called forced labor is nothing but a lie fabricated by certain institutions and individuals in Western countries," he said.

The previous annual high mapped by the Pima County Medical Examiner’s Office in Tucson and the nonprofit Humane Borders was 224 migrant deaths in 2010.

From January to September 2020, the Border Patrol listed 43 deaths in the Arizona border area. Arizona is not the only place with fluctuations in border deaths over the years.

Hundreds of law enforcement officers, National Guard units and a specialized U.S. Border Patrol team, were dispatched to a Houston suburb during the funeral for George Floyd, the man whose death in police custody reenergized national outrage over the treatment of Black Americans at the hands of law enforcement.
