Good morning.

Here’s what you need to know:

Justices back Trump’s travel ban

• President Trump acted lawfully in imposing limits on travel from several predominantly Muslim nations, the Supreme Court ruled this morning. The vote was 5 to 4, with the court’s conservatives in the majority.

The decision, a major statement on presidential power, ends a long-running dispute over Mr. Trump’s authority to make good on campaign promises regarding immigration.

Separately, a California state law requiring “crisis pregnancy centers” to give women information about abortion most likely violates the First Amendment, the justices ruled today. The centers usually seek to persuade women to choose parenting or adoption instead.

Back to “catch and release”

• Many immigrant families who are detained after crossing the Mexican border illegally will be quickly released if they promise to return for a court hearing, the nation’s top border security official has decided, reviving — at least temporarily — the approach used during the Obama administration.
