Here's the problem. There's a big gap between what is appearing in those news shows including affidavits etc - and what the Trump campaign is claiming in court.
Here's an article today in the Milwaukee paper.
A state judge concluded Wisconsin's election was conducted properly Friday, dealing President Donald Trump and his allies their fifth legal defeat in a little over a week.

Quick summary:
"no credible evidence of misconduct or wide-scale fraud" - Judge Simanek
I'll quote the essence of the article:
===
"Trump questioned numerous long-standing election practices. But Simanek found that no violations of election laws occurred.
"(Trump's team) has not demonstrated that an erroneous interpretation of Wisconsin early voting laws happened here," said Simanek.
"Trump argued clerks were wrong to fill in the addresses of witnesses on absentee ballot envelopes. Simanek ruled that policy, which was put forward four years ago by Republicans on the state Elections Commission, is proper.
"The president challenged the ability of Madison poll workers to collect absentee ballots in parks, maintained all early in-person voting in
two counties was illegal and contended voters were given too much latitude to decide if they were confined to their homes. (Voters who identify themselves as indefinitely confined do not have to provide a photo ID to vote absentee, as others must).
On each point, Simanek ruled against Trump and said officials had properly run the election.
In all,
Trump sought to throw out more than 200,000 votes in the two counties,
while letting stand ballots cast in the same fashion in Republican areas.

Pretty much every court case follows this same model - attack that state's procedures, never assert fraud. Lose. That is not a good foundation for the federal case.
