Investigations were performed, hundreds of them. Hell, Trump had a 2 year long investigation into the 2016 election after claiming fraud after winning. They found nothing and had to wrap it up.
You have to provide evidence of your claims, simply making claims isn’t sufficient. The second lawyer is better but he’s going to make emotional appeals rather than arguments.
Trump really scrapped the bottom of the barrel for his lawyer, guy is so out of his depth. The second lawyer is better better spoken but making claims that are directly contradictory and is going to make it emotional rather than legitimate arguments.
Edit - Lol, now he’s saying that it will lead to a second civil war… it’s ridiculous. It’s all a long winded, emotional appeal. Ha, ha, ‘canceled‘, I bet he got payed a bonus for working that in.
