The Trump ambassador to Denmark has complained that her vote wasn't registered and counted.
The Danish media don't believe her, and there seems to be no reason whatsoever to do so:

The US ambassador claims that her vote had not been counted, but it had been counted

All in all, the Danish media find the fraud allegations hilarious:

She apparently made two claims:
That her vote was not counted - which has been debunked here:

That her husband, who has been dead for five years, received a postal ballot. I've not seen evidence to either support or refute that claim.
I take it that she hasn't apologised or corrected herself over her first lie...
