From New Republic:

Indeed, presidents of both parties have tailored immigration policy to their own goals. In 1987, the Reagan administration took executive action to limit deportations for 200,000 Nicaraguan exiles, even those who had been turned down for asylum. Similarly, President George H.W. Bush in 1990 limited deportations of Chinese students and in 1991 kept hundreds of Kuwait citizens from being deported. President Bill Clinton regularly used his power of prosecutorial discretion to limit deportations; in 1993 he gave 18-month extensions to Salvadoran residents, in 1997 he limited deportations for Haitians, and in 1998 he limited deportations to Central American counties that had been devastated by hurricanes.

President George W. Bush also took major steps to limit deportations on humanitarian grounds. In 2001, he limited deportation of Salvadorian citizens at the request of the Salvadorian president who said that their remittances were a key part of their nation’s economy. The Bush administration embraced prosecutorial discretion and ordered the consideration of factors such as whether a mom was nursing a child or whether an undocumented person was a U.S. military veteran in making the determination on whether to order a deportation.

The Bush administration explicitly recognized that humanitarian factors must play into the deportation decision. The 2005 Howard memorandum issued by Immigrations and Customs Enforcement (ICE) stated that “Prosecutorial discretion is a very significant tool ...to deal with the difficult, complex and contradictory provisions of the immigration laws and cases involving human suffering and hardship.” Today, the Obama administration can build on that to stop deportations that separate parents from their children. The breaking up of families due to deportations undoubtedly causes human suffering and hardship: The Applied Research Center in its “Shattered Families” report found that over 5,000 children live in U.S. foster homes because their parents were deported.
