If Cuomo can be charged with crimes for his policy on the nursing homes could Joe be charged should a person gets covid from an immigrant?

You do have a point that this could be a possibility.

At the very least the Federal government could be sued if this were to happen.

You have to prove it first and so far, the media has either ignored the issue, or doubled down on they are all tested prior to release. It does not matter that we have documented cases, like the bus stop, that say otherwise. It does not matter that Biden's administration has gone from all are tested, to the majority are tested, to a media blackout of the issue and what is going on down there.

No to both.  "Can" is the magical word.  Joe?  Do you mean President Biden?  I fail to see the connection between Governor Cuomo and President Biden's policies.
