From Guns.com:

Over a dozen new legal briefs were posted Monday in the case brought by gun owners challenging the constitutionality of the Big Apple’s “premises permit” scheme, a local New York City law that drastically restricts the ability to leave one’s premises with a firearm. The new filings come from five Senate Democrats — Sheldon Whitehouse, Mazie Hirono, Richard Blumenthal, Richard Durbin, and Kirsten Gillibrand as well as 139 Dems in the House, with the lawmakers taking New York’s side.
