The Biden administration will deploy 1,000 military personnel, arriving next week at hospitals across the country, to “enhance surge efforts,” according to the White House official, who spoke on the condition of anonymity to preview the president’s remarks.

Criswell told CNN the teams would primarily consist of nurses and physicians to “provide critical support to help relieve some of the drain and the strain on the health-care system” to fight the pandemic.

Since Thanksgiving, more than 800 military and other federal emergency personnel have already been deployed to 24 states, tribes and territories, the official said. That includes more than 350 military doctors, nurses and medics helping staff hospitals.
