Okay, look at it from a different perspective. Trump has been pursuing legal cases in several states.
He has lost all but 1.
In many of those cases, his lawyers have been asked directly if they have any evidence of voter fraud. They have replied no. He keeps claiming voter fraud but he literally has no evidence.
The Lt Governor of Texas, Dan Patrick, has offered up to $1 million for credible evidence of voter fraud. He still has $1 million.
