Some quotes from the articles linked above:
Samaritan’s Purse, a charity run by Franklin Graham, has set up an Emergency Field Hospital in New York City’s Central Park to treat overflow patients from Mt. Sinai Hospital. Since Samaritan’s Purse isn’t down with the woke agenda de Blasio and other city officials are “very concerned” about the help they’ll render.
Mayor Bill de Blasio said the city will keep a close eye on the Christian fundamentalist group operating a field hospital in Central Park, amid growing fears that some New Yorkers could face discrimination and substandard care from the religious organization.

"We're going to send people over from the Mayor's Office to monitor," de Blasio said. "I am very concerned that this is done right. But if it is done right, we need all the help we can get."
