While in office, the Trump Administration unleashed a series of controversial policies affecting Latinos. On May 7, 2018, Jeff Sessions, then Trump's attorney general, announced a new "zero tolerance" policy at the U.S.-Mexico border, meaning any person apprehended crossing the border without documentation would be charged criminally and any children accompanying them would be held separately. Though the policy was ended by executive order within a month, more than 500 children remained separated from their parents more than two years later. During the 2018 midterm elections, Trump politicized the Central American refugee crisis, claiming "terrorists" and "gang members" were secretly hiding alongside women and children in order to gain entry into the United States. After the midterm elections, the Trump Administration adopted the "Remain in Mexico" program, which essentially sought to shut down asylum entry into the country. The policy resulted in a humanitarian crisis, as tens of thousands of refugees were forced to live in makeshift tent encampments in Mexico while they awaited an asylum hearing. Trump's efforts on the border resulted in the erection of over 53 miles of new border wall and the renovation of over 400 miles of existing border walls; this wall construction sparked outrage for its impact on indigenous communities. During the Trump years, Immigration and Customs Enforcement also collaborated with other U.S. law enforcement agencies, such as the U.S. Marshals, to conduct large "crime raids," during which hundreds of people were arrested and deported if found to be undocumented. In fact, in 2019, ICE conducted the largest single-state immigration raid in U.S. history.
