I’ve only heard Venezuela, not Argentina.
Here’s the transcript for the news conference. Got to 43:56 and you will see that Sidney said this... “In other parts of the world we know that the technology was exported to affect an election in Argentina.”
At 50:21, Sidney says this “There’s no doubt it has been used to alter elections in other countries. We know specifically that Venezuela exported it for that purpose to Argentina and other Latin American companies, to make sure that the corrupt rulers who were willing to pay the highest price for being in office were allowed to rig their elections.”
