MADISON, Wis. — U.S. Sen. Ron Johnson, R-Wis., says the federal government isn’t being honest about the wave of unaccompanied child immigrants crossing the Mexican border.

Johnson said he didn’t learn the U.S. Department of Health and Human Services was asking the city of Madison to look for a 90,000-square-foot facility to shelter 150 to 250 undocumented minors until he spoke this week with Wisconsin Reporter, which first reported those details Tuesday.

Johnson also said he was not immediately made aware of the Federal Emergency Management Agency contacting the Milwaukee chapter of Catholic Charities to find three different sites to accommodate up to 300 children who illegally entered the country.
