The whole point of this was to get people to register to vote, it was basically a DNC registration drive. But NBC made astonishing claims about that and then were still wrong.
Via Daily Caller:
NBC News issued a correction Monday about the number of people registered to vote at the “March For Our Lives” rally in Washington D.C., and still managed to get it wrong.
Originally, NBC claimed 800,000 people had registered to vote at the event. They later put out a correction on Twitter stating 800,000 people were present, but did not sign up to vote. Not only did they fail to provide the number of those who were actually registered, but it also inflated the crowd size by hundreds of thousands people.
