The two slates of certified electors came to DC (that didn’t happen with Arizona in 2020). And that was handled during the electoral vote certification in Congress - which is the time to handle it - not after everything had been certified by Congress and the new president had been inaugurated.
The time for things to have been done to protect against fraud was before the elections took place. I know President Trump’s team knew it was coming. I don’t understand why there wasn’t more actually done before November, 2020.

Well, okay, if you accept that the Constitution honors and legitimizes a stolen presidential election, which means it has been a joke the whole time.
