Supreme Court Justice Samuel Alito is issuing a rallying cry to conservatives in the wake of newfound strength following Donald Trump's election.

Alito tells a conference of conservative lawyers, judges and legal thinkers that religious freedom and gun rights are among important issues at stake in the federal courts.

Alito also is paying tribute to longtime colleague Justice Antonin Scalia, who died in February. The two conservative justices were allies in high court battles on hot-button social and political issues.

Alito says at the Federalist Society's national lawyers' conference in Washington that Scalia is sorely missed on the court and that "we are left to ask ourselves WWSD" — what would Scalia do.

Trump will nominate Scalia's successor after Senate Republicans blocked action on President Barack Obama's nomination of Judge Merrick Garland.
