Arizona sits on the front lines of the nation’s immigration debate. Greg believes the United States can have a secure border while still respecting the rule of law, protecting civil liberties, and living up to our values as a nation of immigrants.​

​

Through his work in Congress, Greg has:

​

• Led efforts to expose and stop the expansion of large immigration detention facilities in Arizona, demanding transparency and accountability from DHS and ICE when federal officials attempted to convert warehouses and other facilities into mass detention centers.

​

• Called for the termination of DHS Secretary Kristi Noem in September 2025 after revealing damning evidence of crime, coverups, and corruption at DHS.

​

• Helped introduce articles of impeachment against DHS Secretary Kristi Noem after deadly immigration enforcement incidents and repeated misconduct within the department.

​

• Helped introduce the Stop Excessive Force in Immigration Act, establishing clear use-of-force standards for immigration agents, requiring body cameras, and strengthening oversight of enforcement operations.

​

• Helped introduce the Protecting Sensitive Locations Act to prevent immigration enforcement actions at schools, hospitals, places of worship, and courthouses.

​

• Co-led the PUBLIC SAFETY Act, redirecting billions of dollars away from detention expansion and toward real community safety investments.

​

• Opposes DHS funding legislation that does not strengthen enforceable accountability and oversight for ICE.

​

• Proud cosponsor of the American Dream and Promise Act, creating a pathway to citizenship for Dreamers and people with Temporary Protected Status who have built their lives in the United States.

​

• Helped lead the development of a new immigration and border security framework focused on modern technology at the border, stronger action against trafficking networks and cartels, expanded legal immigration pathways, and faster, fairer processing of asylum and immigration cases.​

Holding ICE Accountable​

​

• When ICE illegally blocked his unannounced oversight visit to the Eloy Detention Center (July 2025), Stanton didn't back down. He went public, joined a congressional lawsuit against the Trump administration, and promised to return.
   

• Greg made good on that promise — returning to Eloy in August 2025, where he sat down with over 20 detainees, including local business owner Kelly Yu, who had been locked up despite two decades in the community and zero criminal history.
   

• At Mesa Gateway Airport's ICE holding facility in February 2026, Greg and Rep. Ansari exposed alarming conditions, such as people crammed 20-25 to a cell, no beds, no showers, no medical care, and detainees being held far longer than the legal 12-hour limit with no policy to address it.
   

• In March 2026, Greg joined faith leaders, students, and residents to rally against a planned ICE detention facility in Surprise, Arizona, acquired by DHS secretly without ever telling the city, the neighbors, or the school across the street.
