There's also many examples of circumstantial evidence being described. I've seen these on live tV, and some reproduced on videos by Trump's attorneys, them selves outlining such circumstantial evidence. 

There are hundreds of items of direct evidence, including affidavits . This is exactly contrary the rumor(?) of Trump's attorneys saying--no evidence-- in a court.

In the latest Penna case,  I saw reports that the judge declined to hear the Repubs evidence in any detail, and did what amounted to a peremptory dismissal.  Evidence was ready to be presented.

Quote from report:  A federal judge on Wednesday canceled a planned evidentiary hearing on President Trump’s challenge to Joe Biden’s win in Pennsylvania.

Judge Matthew Brann instead gave the Trump campaign until 5 p.m. to respond to a defense motion to dismiss the case, according to an order posted online. 

So there were only lawyers arguments, led by Rudy Giuliani, not the presentation of evidence.  And you know the result was the judge later ordered dismissal. 

The Repubs later have pointed out this is an advantage to their strategy, which is to move the case along as quickly as possible to reach appeals courts and ultimately the Supreme court.
