Rand Paul plans to bring back ‘Remain in Mexico’ policy. What is it?

U.S. Senator Rand Paul announced Thursday that he will soon lead the Senate Homeland Security and Governmental Affairs Committee as chairman, with plans to reinstate the Remain in Mexico policy from the first Trump administration.
Here’s what we know about the commonwealth politician and plans for immigration policies.
Paul said Thursday that, once ratified by Republican members, he’ll be the 15th chairman of the Homeland Security and Governmental Affairs Committee in Congress, with plans to reinstate the “Remain in Mexico” policy for some asylum seekers. The Kentucky senator said Congress must “stand up once again for its constitutional role” and the committee’s mission of oversight and investigations is “critical” to Congress reasserting itself.
“We will also expeditiously move President Trump’s critical nominees, including Gov. Kristi Noem, in time for Inauguration Day,” Paul said.
Justice for Immigrants states the policy requires certain asylum seekers to arrive by land at the U.S. and Mexico border and remain there for the duration of their case in the U.S. immigration court system. The policy was introduced under Trump’s Migrant Protection Protocols program in December 2018, and implemented in January of the following year, sending nearly 70,000 migrants back to Mexico, according to the American Immigration Council.
When Biden took office, his administration suspended the “Remain in Mexico” policy in January 2021 and DHS Secretary Alejandro Mayorkas terminated it in June, according to USA TODAY. The program was later reinstated in November as a result of a court order, returning 7,505 people to Mexico from December 2021 to August 2022 as a result, according to a report from the American Immigration Council.
The court order was eventually overturned by the U.S. Supreme Court in 2022.
