Michigan Democratic Gov. Gretchen Whitmer's order closing public school buildings also bans homeschooling, which is unconstitutional, contends a legal non-profit in the state.

"The Great Lakes Justice Center calls upon Gov. Whitmer to correct this unconstitutional action and assure parents in Michigan that they may continue to safely home school their own children while the EO is in effect," the organization said in a statement Thursday.

The April 2 order states "in-person instruction for pupils in kindergarten through grade 12 … is suspended for the remainder of the 2019-2020 school year."
