US border under pressure as caravan arrived

A soldier from the Kentucky-based 19th Engineer Battalion looks across the Rio Grande River from Laredo, Texas, into Nuevo Laredo, Mexico, where a group of people hang out on the river bank on November 17, 2018. US troops are stringing mile after mile of concertina across various lengths of the US-Mexico border as part of a mission ordered by President Donald Trump to toughen the frontier and provide engineering and logistical support to Customs and Border Protection agents.
