In his new book, longtime investigative journalist John Carlos Frey writes about how U.S. immigration and border policies over the last 30 years have laid the groundwork for what's unfolding at the U.S.-Mexico border today.
The crisis at the U.S.-Mexico border has led to a national debate over what to do about large numbers of Central American families coming to the U.S.
Asylum seekers are being forced to wait in Mexico while their claims are considered as concerns over conditions at border detention facilities are growing.
To understand what’s happening at the border, investigative journalist John Carlos Frey researched U.S. immigration and border policies over the last three decades. That history is part of his new book, "Sand and Blood: America’s Stealth War on the Mexico Border."
Frey discusses his book Tuesday on Midday Edition.
