Governor J.B. Pritzker says the state received the wrong kind of masks from the federal government.
Pritzker made the announcement on Monday in Chicago during his daily press briefing on COVID-19.
Last week, the governor said the White House agreed to send 300,000 N94 masks to the state to help battle COVID-19.
On Monday, Governor Prizker said, the state received surgical masks instead. The N95 masks are considered to be more effective than surgical masks.
