Final answer:
President Obama issued an executive order in 2014 to protect certain groups of undocumented immigrants from deportation and provide them with temporary legal status.
Step-by-step explanation:
In 2014, President Obama issued an executive order on immigration that aimed to give temporary legal status to certain groups of undocumented immigrants and halt their deportation.
The executive order allowed for a program called Deferred Action for Childhood Arrivals (DACA), which protected undocumented individuals who were brought to the U.S. as children from deportation and granted them work permits.
However, in 2017, the Trump administration announced the termination of DACA, leading to legal challenges and ongoing debates about the future of the program.
