Justice Brett Kavanaugh may be joining the Supreme Court just in time to help decide whether President Trump can, at least temporarily, put new restrictions on transgender military service, an advocacy group said on Monday.

A federal appeals court in Portland, Ore., will hear a Trump administration appeal on Wednesday morning asking that a preliminary injunction be lifted so the Pentagon can enforce a policy barring many transgender people from enlisting while the issue is litigated. Four federal lawsuits have been filed and could go to trial sometime next year.
