Respectfully, that's not an accurate depiction of the real events. Biden tried to end the policy in February 2021, for humanitarian reasons, but was sued by Texas and the policy was resumed six months later. The legal wrangling back and forth went on for years. But the bottom line is that despite the policy staying in place all that time, the flow never stopped. The numbers even show that it caused an increase in those who try to enter undetected.
Wikipedia remain in Mexico policy
In February 2021, the administration of President Joe Biden ended the "Remain in Mexico" policy, resuming admission of new asylum seekers and the approximately 25,000 with pending cases to the United States, and asking the
U.S. Supreme Court to dismiss the appeal as moot.
[24][25] On August 14, 2021, a federal judge in Texas ordered a resumption of the Trump-era border policy that required migrants to remain in Mexico until their US immigration court date.
[26][27] The court ruled the reversal may have violated the Administrative Procedure Act, which prevents arbitrary regulations, because it did not consider various facts.
[26] A stay to block reenforcement of the "Remain in Mexico" policy was denied by both the
Fifth Circuit Court of Appeals and the
U.S. Supreme Court,
[28][29] compelling the administration to reinstitute the policy.
[30] In December, the administration announced they had agreed to requirements by Mexico for the resumption of returns, including
COVID-19 vaccination, completion of cases within 180 days, and inquiries into fears of return to Mexico.

After the completion of negotiations with the government of Mexico, the Biden administration announced the resumption of the practice on December 2, 2021, with some alterations.
[31][32] On June 30, 2022, the U.S. Supreme Court ruled in
Biden v. Texas that the Biden administration had the authority to end the policy.
[33][34]
The wind-down allowed migrants into the United States only after their next court hearing, and only if they were not deported.
[35] This resulted in thousands of people staying in Mexico for weeks or months after the program was officially ended, and many missed their court dates due to travel difficulties. One advocate called this delay "a little cruel", and the government was criticized for accepting over 21,000 refugees from the
2022 Russian invasion of Ukraine at the Mexican border during the same timeframe without this restriction.
[35] On December 15, 2022, U.S. District Judge
Matthew J. Kacsmaryk prevented the Biden administration from ending the program, ruling that it should stay in place while legal challenges play out, following the U.S. Supreme Court's decision to return the case to the lower courts.
[36] However, the judge did not order the policy reinstated.
[37] In February 2023,
Mexico's Ministry of Foreign Affairs announced it rejects any efforts to reinstate the policy for asylum-seekers.
