If it was a mistake, then correct it and fire or prosecute those responsible for the mistake.
If no correction is made, I can only conclude the mistake wasn't a mistake at all.
We can revoke citizenship for those who lied on their immigration forms, can we not?

Yes, there is a procedure to de-naturalize these people for a variety of reasons. Chief among them is fraud where they’re found lying on their application. I actually arrested one of these would be “citizens” on his way to his naturalization ceremony. This, of course, was when we were allowed to do our job without interference from the white hut. The fact that people were mistakenly granted citizenship is nothing compared to the fraudulent marriages to illegally obtain permanent residence, but those cases have been determined to be low priority and are no longer investigated. Something else for President Trump to implement after he takes office.

If a mistake - not legal

Not legal - Citizenship can be revoked.

Of course they are LYING.
