Actually the article says the executives may threaten to withhold campaign donations from the two Republican candidates in Georgia. I rather doubt many business executives want to risk having Pelosi in charge of the House and Schumer running the Senate that would be a great example of cutting your nose off to spite your face.What are they going to do file a lawsuit to block Trump from filing them or from filing appeals? I don't think Trumps challenges are going to change anything I never have it doesn't change the fact he has the legal right to contest the election results if he wishes.
The article says they are going to start withholding money from the GOP, particularly for the GA Senate races, if they don't start allowing the transition to proceed.
You can rest assured that will get attention at the RNC and Mitch McConnell.
