BREAKING: Michigan Governor Gretchen Whitmer declares a 3-week lockdown

"The situation has never been more dire," Whitmer said Sunday. "We are at the precipice, and we need to take some action."

Michigan Department of Health and Human Services Chief Medical Executive Dr. Joneigh Khaldun and MDHHS Director Robert Gordon joined Whitmer at the news conference.

“Indoor gatherings are the greatest source of spread, and sharply limiting them is our focus,” said Robert Gordon. “The order is targeted and temporary, but a terrible loss of life will be forever unless we act. By coming together today, we can save thousands of lives.”

All organized sports and group exercise classes will be canceled, but gyms will remain open for individual exercise with strict safety measures.

In addition, casinos, movie theaters, bowling alleys, ice skating rinks, bingo halls, arcades and indoor water parks will have to temporarily shut down, and all businesses are asked to allow employees to work from home if possible.

According to Fox News, gatherings inside homes will also be limited to two households at a time under the new order.

“If you are considering spending Thanksgiving with people outside of your household, I urge you to reconsider,” Whitmer said.

"As hard as it is not seeing [family members] this Thanksgiving, imagine how much harder it would be if you weren’t able to see them for a future holiday ever again,” she added.
