Bozeman, MT -

Justice Antonin Scalia says the U.S. Supreme Court is making decisions that should be left to Congress, from wiretapping to creating special classes of minorities.

Scalia spoke Monday to more than 300 people in Bozeman in an event organized by the Federalist Society.

In an apparent reference to the Supreme Court's recent decisions on gay marriage and benefits, Scalia says it is not the courts' place to "invent new minorities that get special protections."

He says National Security Administration surveillance of phone records and the privacy questions in the Patriot Act should be left to Congress, which knows how to balance the threat against intrusive surveillance.

Scalia also says one of the remaining issues on the Second Amendment is to determine the scope of armaments that people can keep and bear.
