The Trump administration’s U.S. Justice Department on Monday asked the U.S. Supreme Court for argument time to support a challenge to New York City gun restrictions, even though the government has not yet taken a position on whether the case is now moot, as the city contends.

U.S. Solicitor General Noel Francisco, in his request for argument time, said the government has a “substantial interest in the preservation of the right of the people to keep and bear arms.” The government also has a “substantial interest” in defending federal laws regulating firearms, Francisco said.
