On June 20, 2018, Trump bowed to intense political pressure and signed an executive order to reverse the policy[25] while still maintaining "zero tolerance" border control by detaining entire families together.[26][27] When it became clear that this could not be sustained within the scope of court rulings, Customs and Border Protection Commissioner Kevin McAlee announced on June 25, 2018, that the agency would cease referring every person accused of crossing the border illegally for prosecution, effectively ending the "zero tolerance" policy.[28] McAlee said that the policy presented enormous operational and logistical challenges for Border Patrol agents, including overcrowding of children in Border Patrol holding cells while their parents were processed in court and held in immigration detention; federal agents complained of spending "more time processing immigrants than guarding the border".[28] https://en.wikipedia.org/wiki/Catch_and_release_(immigration)#Under_Donald_Trump
