usa – Are Europeans allowed into the US on a B2 visa right now?

I have tried to keep up with the regulations and I have read the presidential proclamations regarding this, and it seems pretty clear, but I am wondering (indeed hoping) I have missed something. It seems Europeans (from the Schengen Area) are indeed presently barred from entering the US. But are there any exceptions for B2 visa holders? Are B2 visas currently being processed?
