New York City Mayor Bill de Blasio, reacting to announcement of a curfew in neighboring Hoboken, New Jersey, says that a lockdown in the nation’s largest city couldn’t be ruled out.

“Every option is on the table in a crisis,” the Democrat said Sunday on CNN.

Also in New York, Gov. Andrew Cuomo said the Army Corps of Engineers should be mobilized by equipping facilities like military bases or college dorms to serve as temporary medical centers.

In an opinion piece Sunday in The New York Times, Cuomo called on President Donald Trump to authorize states to expand testing capabilities, set federal standards for shutting down commerce and schools, and mobilize the military to bolster medical treatment capabilities.

He wrote that “states cannot build more hospitals, acquire ventilators or modify facilities quickly enough,” adding they need the expertise and equipment of the Army Corps.
