The Supreme Court's conservative majority on Tuesday upheld a Texas judge's order that would require the Biden administration to follow President Trump's so-called Remain in Mexico policy.That program sought to deter Central American migrants from seeking asylum in the United States by requiring them to stay in Mexico until their cases were heard in the U.S..The justices by a 6-3 vote rejected an appeal from Biden's lawyers who said the Texas ruling conflicted with the principle that the executive branch has leeway on how best to enforce the immigration laws.
