In this June 18, 2014, file photo, detainees sleep in a holding cell at a U.S. Customs and Border Protection processing facility in Brownsville,Texas. For nearly two months, images of immigrant children who have crossed the border without a parent, only to wind up in concrete holding cells once in United States, have tugged at heartstrings. Yet most Americans now say U.S. law should be changed so they can be sent home quickly, without a deportation hearing. A new Associated Press-GfK poll finds two-thirds of Americans now say illegal immigration is a serious problem for the country, up 14 points since May and on par with concern about the issue in May 2010, when Arizona's passage of a strict anti-immigration measure brought the issue to national prominence.
