Good morning and welcome to Supreme Court Brief. The Biden administration makes its case this morning for revocation of a Trump administration immigration policy–the Migrant Protection Protocols. We take a look at some of the numerous amicus briefs and their counsel. The court, with three justices dissenting, refused to reinstate a district court order blocking a challenged admissions policy at a Virginia high school. The school board's appeal goes forward, but keep an eye on this race-based challenge. Plus, scroll down to read about two interesting petition grants Monday on DNA testing and business jurisdiction.

Thanks for reading. We welcome feedback and tips. Contact Marcia Coyle at [email protected] and follow her on Twitter @MarciaCoyle

Construction is underway to extend a secondary fence over the top of this hill and eventually to the Pacific Ocean.
