There weren't.
If there was nothing to hide there wouldn't be a need to censor it.
All I've heard is claims that there is evidence, none of which has been shared. Or when it has been shared is not compelling.
"Nuh uh"

I too saw (clips of) several of these lawsuits, where Trump advocates were threatened with contempt and finally admitted a complete lack of evidence for claims of fraud.
I also know that elections officials across the country, from both parties, assert there is no evidence of fraud in a systemic manner or in any manner that would change the results of the election.
I also know that the GOP leader of the Senate, the GOP lap-dog Attorney General, and the US intelligence community are in agreement that there is no evidence of the fraud alleged.

Can you please share some credible evidence?
Maybe some of this stuff is debunked but they try to catalog it here.
