The timing had been in doubt since the Supreme Court ruled on June 30 that the Biden administration could suspended the “Remain in Mexico” trump-era policy.
Homeland Security officials had been largely silent, saying they had to wait for the court to certify the ruling and for a Trump-appointed judge, Matthew Kacsmaryk in Amarillo, Texas, to then lift his injunction. The Supreme Court certified its ruling last week. The policy “has endemic flaws, imposes unjustifiable human costs, and pulls resources and personnel away from other priority efforts to secure our border,” the department said. About 70,000 migrants were subject to the policy, known officially as “Migrant Protection Protocols,” from when President Donald Trump introduced it in January 2019 until President Joe Biden suspended it on his first day in office in January 2021, fulfilling a campaign promise. Nearly 5,800 people were subject to the policy from December through June, a modest number. Nicaraguans account for the largest number, with others from Cuba, Colombia and Venezuela. Trump made the policy a centerpiece of border enforcement, which critics said was inhumane for exposing migrants to extreme violence in Mexico and making access to attorneys far more difficult. Homeland Security said it will provide additional information “in the coming days.”
