Officials in Douglas — along the border between Arizona and the Mexican state of Sonora — have declared a state of emergency. The designation could free up additional financial aid from the state and make it easier to impose curfews.

The city’s mayor, Jose Grijalva, says it’s necessary because of policy shifts enacted under President Donald Trump — including his national emergency declaration along the U.S.-Mexico border. Grijalva says those changes stand to hurt his city’s economy, which relies on tourists coming over from Sonora.

“This is an effort to remain guarded, be proactive and create a preventive position for the city of Douglas,” he said.

Grijalva says he hopes the designation sounds the alarm about how federal immigration policy impacts local border communities.
