North Carolina Gov. Pat McCrory on Wednesday signed into law House Bill 318, which protesters today called “the most anti-immigrant bill in the country.” A small group of immigration activists chained themselves together Thursday to block the entrance to the governor’s mansion in protest of the law.

The new law bans North Carolina cities from adopting sanctuary policies for illegal aliens, requires government contractors to check the immigration status of workers, and prevents police and government agencies from accepting IDs issued by foreign governments. A further provision stops the state from issuing waivers exempting food stamp recipients from federal work requirements; unemployed able-bodied adults without dependents face a three-month time limit on food stamps.
