MADISON, Wis. — The federal government has asked officials in the Madison and Milwaukee areas to look for potential sites to house hundreds of undocumented children flooding into the country through the Mexican border.

Madison Mayor Paul Soglin told Wisconsin Reporter Monday the city is working with several organizations, including Centro Hispano of Dane County, to find a facility of at least 90,000 square feet to shelter between 150 and 250 unaccompanied child immigrants.

Soglin said the federal government is hoping to have a self-contained structure ready in the Madison area as soon as possible.
