Remember that after the 2020 presidential election, the Trump campaign claimed the election was fraudulent.
They asked Pence to send the electoral votes of the disputed states back to the state legislatures for reconsideration.
But Pence refused, and Biden's victory was certified by Congress on January 6, 2021.
What's worth noting is what happened next. In 2022, in response to the confusion over the counting of electoral votes, Congress passed the Electoral Count Reform Act.
It made clear that the vice president's role is purely ceremonial, and it wrote into law that the vice president cannot decide election results on his own.
There is no doubt that the way things were handled back then is still a subject of debate today.
If Pence had acted back then, America would be a completely different country today.
