The Centers for Disease Control and Prevention announced in a statement Monday that it was extending Title 42 until the health agency “determines that the danger of further introduction of COVID-19 into the United States from covered non-citizens has ceased to be a serious danger to the public health.”

The order, which the administration of then-President Donald Trump imposed in March 2020, has permitted officials to expel more than 750,00 migrants, according to data from U.S. Customs and Border Protection.

The CDC said Monday that it will continue to assess the impact of the COVID-19 pandemic at U.S. borders and ports of entry and will review updated pandemic information every 60 days “to ensure that the order remains necessary to protect the public health.”
