The University of California, San Diego (UC San Diego) decided to end its participation in a federal program that allowed campus police to collaborate with agencies linked to border security, after student groups organized protests against the partnership.
The institution ceased participation in the ''Operation Stonegarden'', a program of the Department of Homeland Security (DHS) that funds state and local police agencies to cooperate with the Customs and Border Protection (CBP) in border protection. Although a significant portion of the resources is aimed at combating drug and human trafficking, and not directly at enforcing immigration laws, the collaboration generated strong opposition among students.
The University of San Diego police had been receiving funds from Operation Stonegarden since 2012. Part of those resources had been used to patrol coastal areas near the campus, an activity that became the center of criticism from student organizations opposed to the immigration policies of President Donald Trump.

In February, the relationship between the university police and the federal program was confirmed. From then on, students began to pressure university administrators, arguing that the cooperation could ''put at risk'' students who are in the United States illegally and international students.
Aryan Dixit, president of the Student Union for Civil Liberties, stated during a protest that the grants were harming the community and undermining trust in campus police.
